Ignore the wheel event explicitly in order to propagate it further
Qt 6 brings a behavioral change regarding delivery of wheel events:
92df790f46b3a8b17aec2f385d6472fd3f8647f6 and
2a857ee28315c5bacfe2ecaf402ca9005b35c20e. If there is an event
filter installed and wheel event is being processed, the event
is now accepted by default, which means that after returning
true from eventFilter(), the event is not propagated anymore.
Since we want to redirect the event to the parent HelpViewer object,
we explicitly ignore the event prior to returning true.
This patch fixes the QTextBrowser backend.
