           Summary: partial implementation of <datalist> breaks feature
                    detection
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: paul.irish at gmail.com


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)?
