When going to the activity page for any user, the expand/collapse button on larger posts doesn’t work. Clicking it will not expand the post, and only turns the button around and moves it to above the link to the topic. This happens both on desktop and on mobile.
Can you repro this @jomaxro?
I can confirm it on Firefox and Chrome.
When you click the icon the post is not expanded and the icon moves alongside the avatar instead of remaining in its right position
So maybe a regression here @eviltrout?
Pedantically, not a regression because “collapse” is a new feature I added. I just didn’t style it properly in the master branch

This fixes the broken expansion on the user page:
