SUMMARY
Regression from 23.08.4 to all 24.08.1 (same with 24.08.0) - Incomplete video rendering with hidden clip edited in a separate sequence after closing/reopening soft.


STEPS TO REPRODUCE
1. Editing a video in sequence A.
2. Creating the main edit in another sequence B.
3. Adding titles and images to sequence B.
4. Inserting sequence A with numerous effects (notably Chroma Key, Key spill, etc.) into sequence B.
5. Save and exit Kdenlive.
6. Reopen the soft and start rendering.


OBSERVED RESULT
The rendered video does not include the video from sequence A.
Only the other elements edited in sequence B are visible.

And also, I am encountering a problem in the main timeline (sequence B):
   - Either there is a delay between the audio and video of sequence A during playback in the main timeline (sequence B);
   - Or the video from sequence A is completely invisible.


EXPECTED RESULT
The full video with all sequences visible.
