Summary partial implementation of <datalist> breaks feature detection

the webkit impl of <datalist> is not complete. ( see test page: http://miketaylr.com/test/datalist.html ) Meanwhile a few common feature detects pass: 'options' in document.createElement('datalist') // true 'list' in document.createElement('input') // true Luckily window.HTMLDataListElement is still not defined This only seems to affect the Safari port; Chromium is not affected. These passing feature detects make it tricky to test support, so people are using UA sniffing: http://css-tricks.com/15346-relevant-dropdowns-polyfill-for-datalist/ (see "browser version numbers") Could the two above false positives be removed in the meantime while this feature is underway (bug 27247)?

I disabled the <datalist> element for all ports without UI in Bug 82871.
