Top bar doesn't show up in fullscreen mode

[franciszekjuras]

In fullscreen mode the bar on top of the screen autohides (as intended), but it doesn't show back when moving the cursor to the top edge of the screen.

You can delete line 38:

    margin-bottom: -1px !important;

It will show a thin line under the bar but it will behave as you want. I don't use fullscreen so I prefer not having that line.
