Comment (by cypherpunks):

 > Should I conclude that the proposed patch depends on this option to be
 set, and that we have to change it in Tails?

 No no, I just encountered missing 1px when that option is set.

 Could you set extensions.torbutton.loglevel to 3 before startup, and show
 what's logged in these lines

 - "About to resize new window:"
 - "Got max dimensions:"
 - "Resized new window from:"
 - "Mutation observer: Window dimensions are:"
 - "Mutation observer: Window dimensions are (after resizing again):"

 one time with small and one time with regular sized icons (small icons
 would also have to be enabled before startup)?
