Re: [BUG] Org-image-max-width doesn't account for org-indent-mode [9.7.8 (9.7.8-7f2ce8 @ /tmp/bug/elpa/org-9.7.8/)]

[Martin Edström]

To my untrained eye, this bug seems like it must have the same cause as this 
other bug: 
https://lists.gnu.org/archive/html/emacs-orgmode/2024-07/msg00365.html

What I find surprising is how it hasn't been dealt with in 16 years.  Perhaps 
it used to work correctly and only recently broke?

I'm reading the org-indent source code, and it seems to use the Emacs built-in 
text properties "line-prefix" and "wrap-prefix".  So these could be considered 
Emacs bugs rather than Org bugs, possibly.
