Steps to reproduce:
- Have a table with a few headers.
- Click a header and drag it quickly over the other headers, in an attempt to rearrange it.
I have a screen recording of this problem but videos can't be uploaded in this forum.
The dragged header is rearranged to the position where you release the mouse.
The headers that were dragged over get selected. When you release the mouse, the headers remain as they were, instead of being rearranged.
Tested in Google Chrome 83.0 on macOS.
