Comment:
This is easy to reproduce, at least on OSX. It occurs even when e10s is
disabled.
After a window state change (`sizemodechange` event), the Torbutton code
checks for `window.windowState === 1` (which is `STATE_MAXIMIZED`) and
then adds the resize warning notification. In TB 7.0 that state occurs
each time a new window is opened (at least in response to Cmd+N on OSX).
But I don't know why. It seems to have something to do with the anti-
fingerprinting window sizing code, because this problem does not occur if
I set `privacy.resistFingerprinting = false`.
I haven't tested this yet on Linux or Windows.
A side note: it seems like we should add the warning for `windowState ===
STATE_FULLSCREEN` too (but that is a different bug or a design decision
that I am not familiar with).
