Steps to reproduce

According to the specs, and the way all other browsers have implemented it, the user-select:none and -ms-user-select:none CSS properties should NOT allow selection of the contents of the elements that this is applied to:
http://www.w3.org/TR/2000/WD-css3-userint-20000216#user-select

In IE, it DOES correctly block user selection within the element, however it DOES NOT block selection if the user starts above/before or below/after and drags through the element.

  • Hi Stephen,

    Does this happen in IE as well as recent versions of Edge?  Can you tell me the most recent version of Windows 10 you are seeing this issue?

    Thank you for the help,

    Steve

  • Sorry I’m unable to test in the most recent version of Edge (IT lockdown), this version:
    “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2486.0 Safari/537.36 Edge/13.10586” currently exhibits the bug. If someone with the latest build can test and confirm it still exists it would be appreciated.
