Revealer rendering bug

[vafu]

Describe the bug
Reveraler animation doesn't finish completely

To Reproduce
OSD from gjs samples (converted in gtk4)

Expected behavior
Revealer animation finishes and hides the widget completely

Code

Copied OSD from gjs sample and trying it with gtk4 (essentially just convert to ).
There's a rendering bug with revealer animation.
Sometimes it doesn't finish fully, with SLIDE_UP/DOWN transitions it just never disappears from screen. Only CROSSFADE seems to work ok, but as you can see from the video sometimes it is left in a semi-transparent state.

I'm on Hyprland 0.46.0, astal 0.1.0, ags 2.2.1
