Brightness filter gets deleted after undo and redo

[TRA]

Here is how to reproduce:

1. Open an existing project.
2. Open an image or video file.
3. Drag and drop from the source tab in the player to the timeline.
4. Apply a brightness filter.
5. Undo twice. (the drag-and-dropped image or video disappears from the timeline here as expected)
6. Redo twice.

The brightness filter gets deleted.

Maybe related to this bug with the same root cause:

Pasting filters does not create history

Windows 10 x64, Shotcut 25.01.24 Just noticed that after pasting one or more filters, there is no mention of this in the history panel so if you try to undo this action, there’s an unexpected undo of the previous action before the pasting.
