Bug 1998499 [wpt PR 55880] - Add some tests for XML fragment parsing via Element.innerHTML setter., a=testonly
Automatic update from web-platform-tests
Add some tests for XML fragment parsing via Element.innerHTML setter.
I realized both the existing parser glue and the new rust-based parser
glue have bugs here. This adds a test which will hopefully show whether
those bugs are interoperable and perhaps help to fix them.
