[ iOS Sim WK2 ] Layout Test editing/deleting/delete-emoji* is failing

[Truitt Savell]

The following layout tests are failing on iOS Simulator WK2

editing/deleting/delete-emoji-1.html
editing/deleting/delete-emoji-9.html
editing/deleting/delete-emoji.html

Probable cause:

These tests are now a constant failure. This occurred recently by the history.

I'll take a look. I believe these tests need to be rebaselined.

Updated test expectations in https://trac.webkit.org/changeset/243522/webkit while waiting for a rebaseline.
