I believe Georg was referring to the fact that Tor Browser does not
spoof window size. It does, however, return a screen size the same as
the window size, as you have observed. That protects your screen size
from being directly observed when your window is not maximized.

In general, Tor Browser is not trying to blend in with other browsers.
Instead, the goal is to make different users of Tor Browser as
indistinguishable as possible.

Best regards,
