Sounds similar to what we see on bug 1373879.

Hm, whereby this other bug was fixed. Andreas, any idea?

My guess is that we need to use some throttling
like we do for WebDriver:SetWindowRect in
https://searchfox.org/mozilla-central/rev/01d27fdd3946f7210da91b18fcccca01d7324fe2/testing/marionette/driver.js#1360-1409.
This resize/repositioning code could probably be repurposed
directly.

I do find it strange that the stress test for Maximize Window
that follows doesn’t exhibit the this problem, but it could be
a super-rare intermittent.  OrangeFactor seems to indicate it is
pretty rare.

I can look into this after
https://bugzilla.mozilla.org/show_bug.cgi?id=1311041, as it fits
naturally on some of the new browsing context abstractions that
I’m working on there.  Judging by how infrequent this intermittent
is, it’s probably worth waiting for.

And it appears it does have the same problem, as was reported in
https://bugzilla.mozilla.org/show_bug.cgi?id=1380309.

I’ve filed https://bugzilla.mozilla.org/show_bug.cgi?id=1381876 to
ensure the Maximize Window command becomes synchronous.
