Control: retitle -1 pandas: read_html(flavor=bs4) broken with pyside2
This seems to be happen when the tests are run with pyside2 (because of #112*5*222) instead of pyqt5.
I don't know how, given that the traceback doesn't involve Qt at all, but it implies that PYTEST_QT_API=pyqt5 (as in Salsa) is at least a workaround. (I'm not calling it a full fix because I'm not sure if pandas is supposed to work with pyside, i.e. whether it's a bug in itself that it doesn't.)
