CompositorAnimationObserver active for too long error in logs (Button animation stuck for 229s)

### Steps to reproduce

1. Launch Element Desktop on Linux (Ubuntu 26.04, GNOME Shell, NVIDIA GPU)
2. Use the application normally
3. Observe the journal/stderr log output

I have not yet identified a reliable trigger for this issue. It appears to happen intermittently during normal use.

### Outcome

#### What did you expect?
No compositor animation errors in the log output. Button animations should complete promptly.

#### What happened instead?
The following error appears in the log:
```
