Merge with Next Clip moves all following clips on the Timeline

What is your operating system?
Ubuntu Linux 18.04 (Kubuntu flavor) AMD64

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
21.01.29 64-bit

Can you repeat the problem? If so, what are the steps?
Repeatable - see attached video.

When re-attaching a clip that was split by a rippled split-and-move sequence, the selected clip merges properly with the next clip. However, the following clip after the “next clip” jumps forwards to become adjacent to the now-merged clip.

The problem was discovered much farther down the edit process; this video was made by reloading an earlier MLT and then repeating the steps I suspected had caused the problem. I was able to create and un-create the problem then several times, using Undo/Redo. so it is repeatable.

I can confirm this is true and repeatable.
Edit: This actually deletes the clip you’re trying to merge. See Demo 3

1. Color clip on V1
2. Split 3x times any length.

This was removed previously due to bugs, then restored because it was re-requested and I did not reproduce a bug (steps or conditions were not known). Now, people do not understand why it always seems disabled because they want it to act like grouping, which is not what it is. I think I am just going to remove it again.

This is fixed for the next version 21.02
