Description Wenson Hsieh 2017-04-20 10:34:37 PDT 
1. Go to data:text/html,<a href="https://www.w3.org"><div style="display: inline">I am inline</div><div style="display: block">I am block</div></a>
2. Try to drag the link starting from the part that says 'I am block'
3. Observe that the link is not draggable

However, dragging from the part that says 'I am inline' works.

Note: also reproduces on Chrome Canary (60.0.3076.0)
