registration with invite tokens doesn't work consistently
This issue first come to my attention when some user used their invite link on their mobile devices, and the submit button will just do nothing. In the back-end I see that the token is "used" but no account was created. I can recreated this on my phone consistently. I managed to recreate it on my computer twice if I start my browser with a very narrow view-port, but it's not consistent. Using the "desktop mode" on phone will make the registration work, but it's not consistent either.
I'm not certain if this is a FE or BE problem.
p.s. please provide a way to completely delete a user, my instance now have a billion test users I can't remove :(
