This is probably the same issue that causes the error message in [PR 92450](https://github.com/llvm/llvm-project/pull/94250/files#r1624938216) to be wrong.

I can at least change the tag parser to return a NoMatch here, but I suppose the full fix is probably better done separately, like you said there?
