[Bug] Side menu icons and alt text look fuzzy

Issue: The icons in the side menu (default position left side of browser window) appear out of focus if not the active icon. The alt text that appears on hover is out of focus for all icons regardless of active status. Finally, hovering over the current active icon on the side menu changes the icon to appear out of focus like all the rest.

Notes: This has been my experience using Firefox 150.0.2 (64-bit) on Windows 10, which is the most current version. Maximizing the browser window had no change in results.

It may not be a big deal to others, but I live with impaired vision and don't need the extra eye strain.
