[Robert Jenner]

It appears these three tests were added recently, and have been constant text failures since. The tests were added here:

https://trac.webkit.org/changeset/281127/webkit

[Robert Jenner]

The failures were easily reproducible on iOS 14 Production ToT using the following test:

run-webkit-tests --ios-simulator <Insert_Test_Here>

[Robert Jenner]

Rebased tests here:
https://trac.webkit.org/changeset/281168/webkit

Will watch to verify rebase was successful.

[Alex Christensen]

Yep, that fixed them.
