1921928 - Add automated tests of `delete` and `forwardDelete` in `contenteditable=plaintext-only`

Status: RESOLVED FIXED

(Core :: DOM: Editor, task)

Description

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

It seems that Chrome and Safari handle deletion in contenteditable=plaintext-only as same as in contenteditable=true. So, perhaps, we don't need to change our delete handlers, but at least we need to add WPTs for basic cases to check whether it's true.

contenteditable=plaintext-only can have any complicated DOM tree. And there
is no reason to make contenteditable=plaintext-only behave differently from
contenteditable=true when making block empty or joining block boundaries.
Therefore, the tests compares the behavior in the same browser rather than
between browsers. The compatibility between browsers should be tested with
contenteditable=true in the other tests.

Depends on D224188
