The tool tip content size uses an incorrect content margin, when it's
constructed. This content margin has been reset to correct value when
tool tip is positioned using placeTip(). But after that, the content
size not been recalculated.
This patch triggers updatesSize() to calculate content size with
updated content margin values.
