DevTools causes binding errors

[ltetak]

Describe the bug

The UI gets broken when I open some nodes in the visual tree in Avalonia DevTools. I assume that some binding gets broken.

To Reproduce

1. open Avalonia Control Gallery
2. select Panel (see the screenshot)
3. header text disappears
   
4. select the MainWindow node and the header is back
   

Expected behavior

DevTools should not affect the live application in any way

Avalonia version

11.2.0-11.2.3

OS

No response

Additional context

I spent a few minutes investigating this and I guess the problem reveals when there is any relative binding. E.g. this caption

Avalonia/samples/SampleControls/HamburgerMenu/HamburgerMenu.xaml

Line 209 in 151fe00

Text="{Binding $parent[TabControl].SelectedItem.(TabItem.Header), FallbackValue=''}">

I haven't got that far but it is possible that DevTools enumerates properties + gets their values with something being faked and these bindings do not find the parent properly. And this broken value affects the live control as well.
