(cherry picked from commit 351357c3a07b69cf5cf68b03450a084f8dd0344b)
The CSS spec defines the font-size as being a length, which is a
combination of a real number and a unit. This applies to the 'px'
unit as well, so by treating px values as integers when parsing
we were failing to parse not only '12.5px' but also '12.0px'.
The code now uses QMetaType::fromType<qreal> but then sets the
resulting pixel type on the QFont as an integer, as QFont does
not support fractional pixel sizes.
Other code paths in the CSS parsing machinery use QString::toInt(),
either directly or via intValueHelper() or lengthValue(). The font
code path can potentially be ported over to these other APIs for
consistency, but to keep the patch simple this is left for a
follow-up.

These were found with the help of -Wdangling-reference, which is

The one in qtpaths.cpp is a false positive: parseLocationOrError()
returns a reference, so there's nothing for the full expression to
destroy. Moreover, it returns a reference to a static object, so
there's no destruction inside the function either.
The other two aren't, but are also harmless. QDBusMessage::arguments()
and QVariant::toList() return a stored QVariantList by value, so
QList's COW mechanism means at() returns a reference that will not be
destroyed. However, the compiler has no way of knowing that. And
since it depends on the implementation details, change the code to

In Qt 5 style sheets, objects could be selected by an enum-type property
using the integer value of the enum value, e.g
QToolButton[popupMode="1"] { ... }
In Qt 6, the the new meta type system and QVariant implementation enabled
QVariant::toString to return the string representation of the enum value
instead for a property containing an enum. Since QStyleSheetStyle's
attribute matching is string based, this breaks the Qt 5 style selector,
and QCSS code instead needs to use e.g.
QToolButton[popupMode=MenuButtonPopup] { ... }
While the new syntax is arguably preferable, this is an unintentional
change that silently breaks style sheet code (no error or warning at
compile- or run-time).
To support Qt 5-style selectors, we have to change the StyleSelector
interface of the QCssParser API so that we can pass through what type
of value the attribute extractor should return; if an integer string "1"
is provided, then we need to compare the enum integer value; if the
string provided does not represent a number, then we need to compare the
name of the enum value.
Since the pure virtual attribute() method that needs to be implemented
to extract the attribute value of the node is implemented in modules
outside qtbase, add a second virtual method that takes the entire
QCss::AttributeSelector, which includes the value to match. Extractor
implementations can use it to evaluate which type of data to return for
an exact match. The default implementation calls the old attribute()
method so that existing StyleSelector implementations continue to work.
Make the respective change in the QStyleSheetStyleSelector, and simplify
the surrounding code. Adjust other StyleSelector implemnentations in
qtbase. As a drive-by, remove the superfluous virtual declaration from
those overrides.
Once submodules are adjusted to override this virtual function instead
of the (now no longer pure) virtual attribute() method, that method can
be removed.

When parsing CSS, a border-color value is parsed as four brushes, as css
allows assigning up to four values, one for each side.
When applying the CSS to the HTML, we accessed it as a color value,
which overwrote the parsed value with a QColor. So while we had a valid
parsed value (and didn't re-parse), the code accessing that value still
expected it to be a list, and thus failed to retrieve the data.
There are several ways to fix that, but the cleanest way without
introducing any performance penalty from repeatedly parsing (and in fact
removing a parse of the string into a color) is to enable colorValue to
interpret an already parsed value that is a list without overwriting the
parsed value again. To avoid similar issues in the future, add assert
that the parsed value has the right type in brushValues.
As a drive-by, speed things up further by making use of qMetaTypeId
being constexpr, which allows for it to be used in a switch statement.
Add a test case.

There is currently no proper way to change the icon of a

the css property 'qproperty-icon'. But setting qproperties
from the style is not a good idea in the first place, since
it modifies the state of the widget it draws. Moreover, such
properties are only set once (in QStyle::polish()), and
will not have any effect on pseudo states, like hover.
To close this gap, this patch will add a css property
'icon' that can be set on a QPushButton. This property
will follow normal css cascading, and respect pseudo

Notes:
The QTextDocument table model is much simpler than the HTML table model.
It basically only has <table> and <td> support. So the HTML parser is
forced to map markup and styling to the QTextDocument model which
is not without loss.
In other words: While QTextDocument -> HTML -> QTextDocument should
preserve the QTextDocument structure, HTML -> QTextDocument -> HTML
does not preserve the HTML DOM at all.
So for now the HTML importer and writer only support border styles on
