Hi Team,

While going through Blink's commit, I came across another one which was removed from Blink in 2014 and only Safari / WebKit support it right now. (NOTE - it was never standardised).

Test Case - http://software.hixie.ch/utilities/js/live-dom-viewer/?saved=3041

^ Chrome Canary 111 & Firefox Nightly 110 log - 1.0 while Safari 16.2 log 0.5

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/6b76e9c0e649bf8d4b1c6c321af513e0e0c6c1af

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/html/RangeInputType.cpp#125 & https://searchfox.org/wubkat/source/Source/WebCore/html/HTMLAttributeNames.in#367 & https://searchfox.org/wubkat/source/Source/WebCore/html/HTMLInputElement.cpp#795

Just wanted to raise so we can track and remove this non-standard.

Thanks!

Yeah, this seems reasonable to remove. I'd argue Safari is even producing incorrect behavior here given it's ignoring the step attribute.
