Hello,
**Description of the issue: When using private mode only, the history window has the wrong color
How can this issue be reproduced?
- Open Brave and go Settings-> Brave Shields and Privacy → Toggle Private Browsing Only
- Open a random website
- Click on the … menu and select History
**Expected result: The History window should be purple like the Downloads window and the rest of the interface
Actual results: The History window is white
iPhone 11 Pro, iOS 14.3, Dark Mode turned on
**Brave Version( check About Brave ): 1.23.1
Screenshot attached, for comparison also one with Downloads window that has the right color
Thx a lot
