Created attachment 773115 [details] test.html User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36 Steps to reproduce: Web page uses css to stop selectable text in an outer div. If an innner div is selectable has a scroll and the text overflows when you select the select takes the unselectable text in the outer div as well. The test.html attached works with chrome and IE10 but not firefox. Actual results: Using the test.html you can see that you can select text that has been made unselectable by the css if you start within the scrollbox and mouseout. Expected results: The selection should have stayed withing the selectable text.
Confirmed FF 22, Win 7 x64.
No longer reproducing. Text outside of the test case's scrolling element isn't selectable, even when starting the selection inside the element and trying to extend it outside of the element.
