This reverts commit 79e729e1

, which
partially fixed QTBUG-30122 and will need to be reopened.

On the Creator side, we think using the Qt::ToolTip flag is a bit unsafe
since tooltips are supposed to have very limited interactivity. We would
like to propose to use a similar pattern as in QComboBox instead.
