impl_deserialize_for_internally_tagged_enum panic on deserialize when inner element is itself an enum #928
Description
Hi there, pardon the extra context in this example, but please observe this assertion failure: https://www.rustexplorer.com/b/7hmqkv. It seems that parsing is mismatching on open and close tags:
thread 'main' (80) panicked at /home/explorer/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/quick-xml-0.38.4/src/de/map.rs:982:21:
assertion `left == right` failed
left: QName("root")
right: QName("action")
See also how this example, which doesn't have the Create action, works okay: https://www.rustexplorer.com/b/6kiqvq
I don't know how best to account for this difference myself, but I'm guessing it's that the child field of the Create member is itself an enum Element instead of a struct like ElementHolder.
Here is a more complete backtrace if you find it useful:
