[bug] [v2] Issue with Decorations floating above the window on MacOS

[TheSeamau5]

Describe the bug

Background: I am building a multi-page application on Tauri v2

My goal: On some, but not all, pages have the decorations on overlay on the window, no title bar (+ transparency)

Issue: Decorations were floating above the window, out of reach of css

See how the decorations are above the window

This seems to happen whenever decorations were set to false initially (for example in the tauri config) and later set to true

This is how decorations look normally when set to true in tauri config

The problem is that I am trying to set decorations selectively on pages. Some pages will have them and some won't.

Reproduction

Set "decorations": false in the tauri config json and later in JS (for example onMount) call getCurrent().setDecorations(true)

I have also noticed it happen when:

1. Set "decorations": true in the tauri config json
2. Set getCurrent().setDecorations(false) on mount
3. Later in program set getCurrent().setDecorations(true)

Expected behavior

The expected behavior is that the decorations always show up inside the window and never above, regardless of the previous state of the decorations or how often it was toggled true and false.
