bug: Inspector border overlaps the header

[mattmilesi]

What happened?

When the Inspector (right sidebar) is opened, it overlaps the header.
It's only the border and a small background color change, just a UI issue, no feature is broken.

Environment

0.15.0 / macOS 15.5 / Apple Silicon

In version 0.16.1 I still have the issue.
