Steps to reproduce:

1. On this very page press F12 to open Developer Tools Panel and choose DOM (you need to enable it via the Toolbox options (the gear icon) if it's not there).

2. In the input field in the upper-right corner enter "window" (w/o quotes) to filter the properties list.

3. There will be only one entry left, specifically the property "window", with the arrow on the left for expanding it.

4. Click the arrow. An indentical entry will appear, and so forth.

I might be wrong though, and it's not a bug, but something that has to do with the window object self-referencing.

This is not a bug. The |window| object has a property |window| that refers to the window object itself.

You might see this MDN page:
https://developer.mozilla.org/en-US/docs/Web/API/Window/window

So, as you expanding the window object you see the prop that can be further expanded and so on ...

I am closing the report now, but feel free to reopen in case I missed something.

Thanks!
