Hi Team, While going through Blink's commit, I came across another failing test: Test Case - https://jsfiddle.net/gk3wLomf/ ^ Fails in Safari 26.1 and passes in Chrome Canary 144. Blink Commit - https://chromium.googlesource.com/chromium/blink/+/43f2b197f78550562b865c3abea7dc9844f147ba Just raising so we can track and fix it. Thanks!
