It's the only case where after evaluating "false && true" you have to first evaluate a whole other command, the loop condition, before deciding whether you trigger an ERR_EXIT for the "while".

Yes, that's quite likely, but you're finding that with code that's
already broken (fails multiple C03traps tests).  You can run
  make check TESTNUM=C03
  make check TESTNUM=E01
to determine whether an experimental change is going to regress a
different variation.

It isn't really helping to repeat the observation that the behavior is
not as specified; getting the internal state to reflect "instead
bubbles up" is exactly the complexity.
