In the profile dropdown menu, the "Log out" option doesn't turn your cursor into a pointy finger when you hover over it. Maybe some other buttons don't do this either, but I'm not sure. This css fixed it for me:

button {

cursor: pointer;

}

And here's a screenshot to top it off:

Also, the formatting buttons appear to be activated after moving your cursor to a spot with no formatting using the mouse, they only change to look correct after keyboard input.
