The bug
While teleporting between dimensions using /execute in <dimension> run teleport @s (or similar) the client got stuck at the "Loading terrain..." screen when I teleported from the overworld to the nether (previous teleports were successful). However it remained responsive.
It appears the underlying problem is that the server got stuck while performing the command (see attached jstack outputs):

The following might have been logged after using the command, though I am not completely sure and it might be the log messages of a previous teleport:

Forcing a crash failed, the client became unresponsive after logging "[CHAT] [Debug]: Crashing in 1...". The thread dump for this is force-crash-hang.txt
