           Summary: "-webkit-user-select:none" is not always honored when
                    selecting parent (or ancestor) DOM elements
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
               URL: http://jsfiddle.net/yWjCG/4/
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: csillag.kristof at gmail.com


When selecting parts of the DOM using the selection API, and then reading back the selected content (with the selection API), content that is configured as non-user-selectable (by adding user-select:none in the CSS) is sometimes included.

I have not been able to exactly pinpoint the circumstances that trigger this.

For an example, see this: http://jsfiddle.net/yWjCG/4/

In the linked test, "Test level 3" and "Test level 2" omit the non-user-selectable part of the text, as specified, but "Test level 1" includes it in the selection, which seems to be a bug.

Firefox does this right. (It omits the non-user-selectable text in all test cases.)
