  Oh, damn. Sorry, I've missed those.
  As for `isDesktop()`, I've just moved it to the second patch, since it's related to the bug 390366. I hope it's not a big deal.
  I'll make readability changes you've mentioned in a separate commit then.
  
  BTW, should it be backported to 5.15 or something?
