This test is constantly failing with a text diff on iOS.

REPRODUCIBILITY:

I was able to reproduce this issue on the iOS 17 Simulator (17.0.1 / 21A340) ToT using the following command:

run-webkit-tests --ios-simulator --clobber-old-results --verbose --no-new-test-results --force fast/forms/input-baseline.html

REGRESSION:

This test has been constantly failing since iOS 13 at the latest. As the failure has been occurring prior to the earliest results dashboard entries, I am unable to definitively locate a regression point for this issue.

NOTES:

A test expectation has already been set for this issue, but the contributor did not create an issue. It appears the commit that added it was 157624@main.
