Well, in general I would have assumed to be able to get alias decl of tmpl. Wasn't able to find a simple way to get it.

Defaulting to innermost_template_args looks indeed a bit wrong, but seemed to work.
It's wrong, it just papers over the bug. There shouldn't be a mismatch at this point.
The problem seems to be that most_general_template isn't actually returning the most general template, so we're trying to instantiate the partially-instantiated alias template with a full set of arguments: thus the mismatch.
