Hi Koen!
Thanks for following up.
Please let me emphasize that my issue not urgent, and not really
important in any way. I'm just playing around with Wt trying to
learn what it does and how to use it. So I appreciate your advice,
but I'm not making any specific requests.

Please let me clarify to be sure I understand:
1) To use animation, I need a non-inline widget, e.g. setInline(false);
But
2) Even with setInline(false);, my use case -- hiding and showing the
same widget repeatedly -- is not expected to work correctly because
of the bug you mention below.
Is this correct?

Again, just to confirm, does this bug mean that my test program is not
expected to work (even with setInline(false);)?
Is the bug fix simple? Is it something I can hand-patch in my build of
Wt 3.3.3?
I did add setInline(false); to my test program, specifically:
AnimateTest::AnimateTest (const WEnvironment& env) : WApplication(env) {
showButton_ = new WPushButton ("Show", root());
hideButton_ = new WPushButton ("Hide", root());
new WBreak (root());
text_ = new WText ("show / hide text", root());
text_->setInline (false); // <-- only change to test program
showButton_->clicked().connect (this, &AnimateTest::show);
hideButton_->clicked().connect (this, &AnimateTest::hide);
}
void AnimateTest::hide() { text_->hide(); }
void AnimateTest::show() { text_->animateShow (WAnimation
(WAnimation::SlideInFromRight)); }
I still see the same behavior -- the text does not reappear after the
second attempt to show it. (I only checked ie and chrome, and both
show the same behavior.)
