A minor cosmetic issue regarding Modern UI.

Does this issue occur when all extensions are disabled?: Yes

- VS Code Version: 1.132.0 and later
- OS Version: Ubuntu 24.04.4 LTS 7.0.0-28-generic

Steps to Reproduce:

1. To reproduce, open VSCode and enable the experimental feature "Modern UI".

In version 1.131.0 and earlier, the close button (X) on the file tabs was positioned to the right of the filename and the Git status icon:

However, in version 1.132.0 and later, the close button overlaps with the filename and the Git status icon:

This causes the filename to be obscured when the mouse hovers over it. After the mouse cursor moves away, the empty space on the left side of the icon and the right side of the filename end up with different lengths (personally, I find this aesthetically unpleasing).

Is this a bug or intentional? If it's the latter, would it be possible to consider adding a setting to revert this behavior?
