Steps to reproduce:

1. Create a new Unity project
2. Go to Window -> Multiplayer -> Multiplayer Center
3. Verify that the mentioned window becomes visible
4. Select "Adventure" in the "Genre of your Game" dropdown
5. Select "2" in the "Number of Players per Session" dropdown
6. Install all recommended packages
7. Close the "Multiplayer Center" window
8. Go to Window -> Multiplayer -> Multiplayer Tools
9. Observe (?) the help icons

Actual results: Help icons in a dark Unity theme are poorly visible and are inconsistent with other icons in this theme. A screenshot is added below in the "Attachments" section.

Expected results: Help icons should be in a different background as they are in the "Inspector" and other tabs.
