White line under bookmarks bar with Th24 enabled and Web Store themes applied

[Amanoki]

System Details

• OS: Windows 10
• Thorium Version: M126.0.6478.251

Problem
Steps to reproduce:

1. Fresh install, enable chrome://flags/#thorium-2024, enable Show bookmarks bar.
2. Install a theme from Chrome Web Store, such as this one.
3. A white line shows up under the bookmark bar.

Note: Not all themes have the issue, but the ones that do are quite a lot, it should be easy to see it by installing random themes.
The white line does not exist when Enable Experimental Thorium 2024 (Th24) UI is disabled.

@Amanoki OK thanks. I'll look into it for the M127 release.

@Amanoki Can you enable the chrome://flags/#force-disable-tab-outlines flag, and see if it fixes it?

Enabled it (no tab outlines) on BETA 2, the bookmarks bar white line is still there.

P.S. Tried out BETA 2 and I love the context menu btw, other features look good, thanks for the fixes!
