Bug 264673

Hi Team, While going through WPT failures, I noticed that we are failing two test cases: Test Case: https://wpt.fyi/results/html/dom/idlharness.https.html%3Finclude=HTML.*?label=master&label=experimental&aligned&q=safari%3Afail%20idlharness >> HTMLTextAreaElement interface: operation setSelectionRange(unsigned long, unsigned long, optional DOMString) >> HTMLTextAreaElement interface: calling setSelectionRange(unsigned long, unsigned long, optional DOMString) on document.createElement("textarea") with too few arguments must throw TypeError ___ Web-Spec: https://html.spec.whatwg.org/multipage/form-elements.html#htmltextareaelement Current: [ImplementedAs=setSelectionRangeForBindings] undefined setSelectionRange(optional unsigned long start = 0, optional unsigned long end = 0, optional DOMString direction); to [ImplementedAs=setSelectionRangeForBindings] undefined setSelectionRange(unsigned long start, unsigned long end, optional DOMString direction); It compiles and progress both above test cases ____ Just wanted to raise so can fix them. Thanks!
