1676295 - Add WPT to check deleting in/around/across list item elements

Status: RESOLVED FIXED

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Blink and WebKit behave better than Gecko. They keep list items when deleting (especially when the last) list item element. Gecko should follow it (in bug 1672900), but first of all, we should create WPT.

Attachment: Bug 1676295 - Add WPT to test deleting in/around/across list items r=smaug!

There are not enough tests comparing delete operation result and result of
getTargetRanges() when selection is in/around/across list item elements.
This patch creates a utility method to make the test body not need to use
Selection API for making simpler tests.

The expected behavior is based on Blink and WebKit unless their behavior is
buggy because their behavior is more reasonable than Gecko's in most cases.

Note that the removing tests are covered by the new tests.
