Comment:

 If you open any toolbars after creating the window, your resolution will
 be the new content window size. We could try to resize the window again on
 these events, but I'm not sure it is worth it, since the intermediate size
 might still be detected by content. Certainly seems like a separate bug to
 handle that case anyway.

 For this bug, I'm more interested in understanding the cases where a brand
 new windows are weird sizes.

 Also, please don't set priorities on bugs to high levels just because they
 personally annoy you. I do not believe that allowing a website to
 temporarily see that you resized your browser window is a "critical"
 fingerprinting vulnerability, especially since the website is not given
 information as to if this was a toolbar being opened vs any other type of
 window resize.
