Looks good. not sure, but should this be in test_backend_tools.py?

I put the test in test_backend_tk.py as this was a bug related only to TkAgg AFAIK. The actual bug fix is in _backends/backend_tk.py.

Thats probably fine, but is the same bug present in other backends?

As the bug stems from the backend_tk.py file It would seem the bug would only affect this backend. Additionally, I just tested with qtagg and PyQt6 and there is no bug on the main branch.

Thats great - however, does the test apply to the other backends? If so, perhaps better to put somewhere that all the backends get tested to increase our test coverage? BTW, I haven't checked all this, so feel free to tell me the test is definitely only useful for Tk and I'm happy to approve - we can always generalize the test later if you are not correct.

Indeed, this test could be applied to any backend! You are right that it would be more useful if I can parametrize the test for any backend. Although I am not familiar with the whole set of matplotlib unittests. Do you know if there are tests that parametrize over backends so that I can generalize the one I introduce here? Thanks

I used the parametrization defined in test_backends_interactive.py in order to get environments with different backends and run them in a subprocess helper function. The parametrization now gives ~13 tests for different configuration. I tested with pyqt6, pyside6 and pycairo installed in my environment and it seems to work. I couldn't make it work with pyqt5 and other pysides as I had trouble installing these packages.

Oh it seems there is a very similar bug in the wx backend seen on appveyor. I could reproduce it locally and fixed it. I'll push the fix.

Sorry for the conflicting informations, but I think this test should rather go into test_backends_interactive.py::_test_interactive_impl. This is because interactive tests are very, very slow to start up (as they need to be run into their own subprocess) so it is better to try and minimize the number of tests and do more in a single test. Probably we should better document this at the top of test_backends_interactive.py...

Sure I'll move it there

I'm not an expert on how the tests are structures (obviously 🐑), but this looks good to me. Perhaps @anntzer will have a minute for a second review.

Modulo sorting out the extra try/except added in the test.
