Describe the bug
I have a tween with a clip. When dragging the said clip, it disappears with the error :
TypeError: clip is undefined index.js:37
Error Details:
Object { error: "TypeError: clip is undefined", url: "https://www.wickeditor.com/editor/corelibs/wick-engine/wickengine.js", line: 56683 }
index.js:37

To Reproduce
Steps to reproduce the behavior:

1. Open the attached file.
2. Click "Preview Play". Everything's fine.
3. Move time to 35.
4. Go to layer "Ballon" (ball).
5. Move the red circle.

Expected behavior
The "ballon" clip is moved, creating a new key-frame.

Actual behavior
The circle disappears, with the error in Firefox 112.0.1 :
