When hovering over a tag, the text inside becomes unreadable because the text and background color are too similar:

![Unreadable blue tag][1]

**Edit:** <s>Looks like this has been fixed.</s>

**Edit 2:** The problem is isolated to favorite tags. Hovering over a favorite tag is subject to this issue; non-favorite tags are not affected.
