User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170809204109 Steps to reproduce: 1. Open a HTML file containing: <ol><li><a href="http://localhost/">This is a link</a>.</li></ol> 2. Try to select the beginning of the text of the link, starting just before the link. Actual results: Nothing happens (nothing is selected). Expected results: The text should be selected. Note: If one starts before the "1.", this works, but doing this is counterintuitive.
