    <thetext>Description:
fast/forms/scroll-into-view-and-show-validation-message.html
fast/forms/textarea-scrolled-endline-caret.html

The first failure I saw on the dashboard was on 5/19/2022 at r294525.  r294523 modified updateLayout() via HTMLTextAreaElement::childrenChanged, caused the tests to fail and others and reverted at r294550. The tests begin passing consistently again until r294610 and then begin flaky failing.  

REPRODUCTION STEPS
I can reproduce this on r294610, but unable to reproduce it on r294609 or earlier.

Command: 
run-webkit-tests --debug -1 --root 294610-debug --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 250 -f --no-retry fast/forms/scroll-into-view-and-show-validation-message.html

Result: 
Unexpected flakiness: text-only failures (1)
  fast/forms/scroll-into-view-and-show-validation-message.html [ Pass Failure ]

History:
https://results.webkit.org/?suite=layout-tests&amp;suite=layout-tests&amp;test=fast%2Fforms%2Fstate-restore-to-non-edited-controls.html&amp;test=fast%2Fforms%2Ftextarea-scrolled-endline-caret.html&amp;platform=mac&amp;flavor=wk1&amp;limit=50000
