Subject: Fix test failures with pytest 8.4
https://github.com/pytest-dev/pytest/pull/13380 (I think) means that
pytest now fails if all the traceback frames after the cut have
`__tracebackhide__ = True` set. To avoid this, set `__tracebackhide__ =
False` if we're about to raise an exception directly from the plugin.
Fixes: #151
This may need to be fixed in pytest instead; see the upstream issue.
Origin: other, https://github.com/python-trio/pytest-trio/pull/152
Bug: https://github.com/python-trio/pytest-trio/issues/151
Bug-Debian: https://bugs.debian.org/1114324
Last-Update: 2025-09-18
