[BUG] Tab width in Org files must be 8, not 4 [9.7-pre (release_9.6.13-995-g1d7297 @ /Users/michael/.config/emacs/straight/build/org/)]

[Michael Dixon]

After a recent update, when I am editing a bulleted list (with an indent
of 2 spaces, like you can see in the Org manual), I get the following
error when I press <RET>, M-<RET>, etc.:

Tab width in Org files must be 8, not 4

This happens within any heading in which the bulleted list exists. If I
create a new heading, I can type text and paragraphs there with no
issue.

I just noticed this today, though I don't often use plain lists, so not
sure if it has been happening for longer.
