Wt

With wt 4.0.5-rc1 there is a regression with WStackedWidget height in the presence of fade animation. I believe this is the same issue reported in #6732. It can be reproduced with the wt-homepage example. Deployed at "/test", the following should be observed:

1. Visiting /test will work correctly
2. Clicking on the "Features" menu item will truncate the contents of the features page (though this may not be obvious)
3. Clicking on the "Support" menu item will display with excessive height (blank area above footer)

The above sequence will display correctly if animation is disabled, e.g. by commenting out line 133 in examples/wt-homepage/Home.C, or if a version of Wt prior to e771d6ac is used (as pointed out in #6732).
