Inconsistent icon highlighting #3727
Description
While in the Amanita theme looking at a Project index page, I noticed that the edit icon becomes almost unreadable when it gets highlighted. The other icons on this page do not change their background. I then looked at a show observation page and noticed the same behavior for the edit icon there as well. The pagination icons, on the other hand, change their background but also their foreground. Finally the notification icons, just change their background, but it works due to the icon design. I also noticed that the pagination icons appear in round rectangles while the other icons are in square rectangles. Personally I prefer the round rectangles, but consistency seems more important than any specific design choice.
