Thank you for the explanation. The short-term fix works, but is noisy. Furthermore, it seems that it *must* be executed at toplevel : wrapping it in a function and calling this function doesn't work. So including it in a startup file doesn't seem reasonable.
The issue you pointed has been closed on Jan 6, 2023. Do I need to create a new issue for this problem ? BTW, diagnosting the problem is complicated by this issue <https://github.com/sagemath/sage/issues/30661>, which seems to be at the bottom of the stack...
