'macOS' appears in the documentation frequently, and because it
resembles a variable/property name, QDoc links each occurrence
of it.
'WebChannel' appears as part of a module name, but it's also
a QML type - auto-linking each word to QML documentation is
confusing.
Likewise, there's no need to link 'OpenGL' each time.
Explicit links such as \l [QML] WebChannel continue to work.
