if you load a scene with an already-defined timeline, then reset the scene with reset button, some timeline elements will remain within it. duration never goes back to 10 seconds, and all the camera and time scale data remains, which means things will keep accumulating if you keep doing it, especially if you then save the scene card. the most affected examples of this are by https://www.pixiv.net/artworks/120582913

this scene card is over 70 mb of trash data stuck in the timeline. if you change its duration to around 5 minutes, select all camera nodes and delete them, it will keep working for around 10-15 minutes until it finally purges all the stuck timeline data, and resaving it the same scene will now be below 3 mb. (edit: ok, this one is nowhere near most affected. at one point i had a scene that was nearly 1 gb because of all that)
this is right after one scene was reset:

and this is after it was saved and reloaded:
