                    imported/w3c/web-platform-tests/html/dom/idlharness.ht
                    tps.html is consistently Failing
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW

The following layout test is failing consistently on iOS 13:

imported/w3c/web-platform-tests/html/dom/idlharness.https.html

This test was previously crashing. The crash was resolved in r251057, uncovering that the test is constantly failing.

Steps to Reproduce:

The following command results in crashes before r251057, and failures on r251057 and forward:
run-webkit-tests --ios-simulator --no-retry imported/w3c/web-platform-tests/html/dom/idlharness.https.html --iter 20
