Bug 202960 – [ iOS13 ] Layout test imported/w3c/web-platform-tests/html/dom/idlharness.https.html is consistently Failing

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Russell Epstein]

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

Updated TestExpectations in r251107

> Updated TestExpectations in r251107

This needs a platform-specific baseline. Updating TestExpectations is definitely not the right thing to do here..
