I'm unable to reproduce this on Ubuntu 20.04 with 5.8.1.2-test.

I vaguely recall there's actually a bug in some version(s?) of "less"
that causes its parent to exit?

I did discover that if "less" exits with an error, the whole pipeline
becomes unkillable with either INT or QUIT; the shell is hung until
the left side exits.
