User mention dropdown: too small
The UI for the user mention feature is cramped and showing only one person at a time (only when another post is directly below the comment input field or when the bottom of the browser window is directly below).
(In the screenshot, there are 5+ users selectable but the display box is only big enough to show one at a time)
And sometimes even when there is only one person in the search result I still get scroll panels.
Got the issue and we will fix it in the next version.
