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.

You are right.
Stefan, I reverted that change and I'm reopening bug#48639. This
problem is a much more serious regression than what happens sometimes
when text-size is scaled. We will need to find another fix for that
bug, most probably in one of the hooks used by tabulated-list.el, by
adding the display property only when actually needed.

To help debugging the original problem: the 'display' property that
was always present caused move-to-column in tabulated-list-print to
stop at the wrong position, where the tabulated-list-column-name
property had the wrong value. So either the 'display' property should
be used only when actually needed, or the tabulated-list-column-name
property should be also put on the text covered by the 'display'
property.
