bug#53133: 28.0.90; tabulated-list-sort doesn't work as expected

[Shingo Tanaka <shingo.fg8@gmail.com>]

Hi,

tabulated-list-sort sometimes doesn't work as expected due to the change between
28.0.90 and 28.0.50.

Here is how to reproduce:
1. Open Emacs from terminal with `emacs --no-init-file'
2. Type M-x list-buffers
3. Type C-x o (go to Buffer Menu)
4. Type C-M-Right 5 times to move on to "Fundamental" in "Mode" column
5. Type S 2 times or more to toggle sorting order
6. You will be able to see that "Size" column is selected as the sorting column
   unexpectedly

Looks like below change from 28.0.50 is releated to this issue, because it
disappears when I just rewind this change.

Hope this will be fixed appropriately in the coming major release.
