Comment (by cypherpunks):

 For context, Atlas adopted the zero-width space solution in #12685 but
 moved away from it in #21350. #21459 was solved by simply adjusting the
 styling so I'm not sure if its solution is relevant to this ticket.

 See the inline patch for my proposed solution. This patch allows browsers
 to wrap the fingerprint on any character. Selecting the fingerprint is
 possible by double clicking (or triple clicking when it's wrapped) and
 when copying and pasting the fingerprint it does not contain any spaces.
