LPS-42170 - The first contents in the control panel don't have a hover text description if minimizing the menu bar

Hi @natecavanaugh,

Attached is an update for https://issues.liferay.com/browse/LPS-42170.

I removed the :before selector from the control panel minimized nav.  I wasn't sure what it was originally there for, so I checked with Patrick and he thinks it just got left in there by accident when we switched from fonts to images.

I also will be sending you a pull for liferay-portal-ee/ee-6.2.x, because the issue exists there as well but requires a slightly different fix.

Please let me know if there are any issues.

Thanks!
