Attachment: Bug 1776332 - part 1: Create a tentative WPT to check attribute handling of splitting element by the builtin editor r=m_kato

We have similar tests under mozilla. However, for Interop2022-editing, we
should rewrite it with the modern style and mark it "tentative".

It does not matter how to split an element and its ancestors here. The test
check only how attributes of splitting element and its ancestors. All
attributes should be cloned, but id attributes shouldn't, at least, there
should not be 2 elements which share same id value.

Chrome duplicates id attributes, so Chrome fails to pass of the checks, but
passes the other checks.

Depends on D150219

Attachment: Bug 1776332 - part 2: Create a tentative WPT to check attribute handling of joining elements by the builtin editor r=m_kato

Similar to the previous patch, this adds tentative tests. Different from the
previous tests, joining shouldn't touch attributes of the original nodes.

This tests do not check which node is deleted from the document, but in the
future, it should be tested after fixing bug 1735608 completely.

Depends on D150220
