Description of the bug

When using a revealer widget, animations seem to have a fixed frame count. That is, whether the animation is set to have a duration of 100ms or 5000ms, it's only gonna be 5 frames.

Reproducing the issue

Use a revealer widget, fiddle with parameters, profit.

Expected behaviour

I guess it should have a fixed framerate rather than frame count.

Can't seem to reproduce this 👀

Ok so without a defined :transition property, you get the default opacity transition, which is fine, but when you specify a different :transition it'll be affected. slide-down etc do have a fixed frame count.
