[issue17088] ElementTree incorrectly refuses to write attributes without namespaces when default_namespace is used

[Wim]

Wim added the comment:

FWIW: I noticed that my patch has a bug due to sharing the cache dict between element names and attribute names, although I think this is unlikely to crop up very often in practice. I'll submit a better patch if/when I get the time to put one together.
