Broken off from bug 13106. A few key questions: 1. What counts as a number (leading/trailing junk, hexadecimal, non-integer, etc.)? 2. Should collection(argument) match collection[argument] or collection.item(argument), or should all three match? 3. Should collection.item() handle two arguments or only 1? 4. Should collection.item(argument) return null or undefined when argument is not found?
Created attachment 13696 [details] testcase for null-like arguments
Created attachment 13697 [details] test case for numeric arguments
We need to write a test for question 3. I think the rest are covered.
Safari 15.5 on macOS 12.4 matches with other browsers (Firefox Nightly 104 and Chrome Canary 105) in the attached test cases. I think they were fixed along the way and this bug can be marked as "RESOLVED CONFIGURATION CHANGED". Thanks!
Oh yeah, we improved this area some time ago.
