This isn't reproducible with Bash 5.0 or Bash 4.4.
It's not a signal blocking problem. It's a combination of an interactive
shell and the shell forked to run the command substitution inside the shell
forked to run `cat', which is running the redirection. The issue is that
the child running the command subsitition is not placed into the correct
process group, so its process group is not the same as the terminal's. It
should join its parent's process group.
