Details

+++ This bug was initially created as a clone of Bug #1420590 +++

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20171024165158

Steps to reproduce:

  1. download the attachment and open it in Firefox.
  2. drag something into the page and then drag out.

Actual results:

When dragleave fires, the event.target is set to document (if e10s activated) or XULDocument (if e10s not activated; and accessing event.target throws an error in this case).

Expected results:

The event.target should be the .dropmask element. (in other browsers)
