Editing a post and saving it keeps the transparency even after saving. You need to refresh to see the post normally. First posts in a topic aren’t affected but subsequent ones are.
Instagram links no longer get a onebox - just show up as a link.
@sam its happening on Meta with both Firefox and Chrome. It only happens when you edit a post and save without making any actual edits (just click save without changing anything).
The strange thing is that its only happening with some posts - for example, it doesn’t happen on this post - maybe because its still under the 5m edit time? EDIT: Yep, does this after the 5m editing time has elapsed. If you try it on your post now it should reproduce the bug.
Hmm still not happening for me, but @nbianca has a related fix, merging it now, should be live in 20 minutes here. Let me know in an hour or so if this persists.
