Interestingly dash/ash does not exhibit this behaviour. Looking at the
implementation since 1994 shows that it issues SIGCONT unconditionally
after TIOCSPGRP:

The prior art suggested by dash/ash is that bash should send SIGCONT
unconditionally after tcsetpgrp() when moving a program to the
foreground.
Thanks for the report. Let's try it, since sending SIGCONT to a process
should not have any negative side effects.
