This question looks like this in the editing preview:

preview with working lists

Here the #) list formatting works. But when the question renders on-site, it looks like:

render with non-working lists

The #) list has lost its formatting and shows up as plain text. I believe the style of #) is supposed to work for numbered lists, or at least I recall seeing it before. Why does this happen?

(The other kind of numbered list formatting - #. - still works)

Examples on a fresh post:

Ordered list using #.
  1. List item 1 with 1.
  2. List item 2 with 2.
  3. List item 3 with 3.
Ordered list using #)

Does display as a list in preview.

  1. List item 1 with 1)
  2. List item 2 with 2)
  3. List item 3 with 3)

    I don't see anything in the help pages indicating that the #) format should work. OTOH, it is part of Commonmark, so I would expect it to work, given that SE is supposed to be using modified Commonmark at this point.

  • @Makyen yeah, I couldn't find it documented anywhere either. However I remember it working before, and it works in the preview, so *shrug* bug report.

  • The examples edited into the question works... huh?? (I was going to protest that examples weren't needed in the question itself, but now this is intriguing)

  • Ohhh... I didn't go to the question you linked. It was last edited when it was posted in 2018, so it's never been re-rendered using the Commonmark Markdown converter. So, just save an edit.

  • @Makyen that fixed it. Feeling a little silly now :) Any opinion on what to do with the meta question now?

  • If you don't want to delete it, I'd rewrite it to more accurately reflect the issue: old post not rendered under Commonmark, makes it look like there's some problem with formatting, with the additional strangeness that it's OK in the preview. Then you can just self-answer that it can be fixed by re-rendering, which is triggered when a new revision is saved.

This problem is caused by the #) style not working before the Commonmark migration. Since this particular post hadn't been edited since the migration, it hadn't been rendered with the new formatting. Editing to force a re-render fixed the problem. The preview works because it's Commonmark compliant.

  • There's a number of posts where this is the case, including posts using code fences before they were supported. Manual cache kicking is necessary, unfortunately Jul 20, 2021 at 9:58
