Mozmill's 2.0 dnd_chrome.js test sometimes fails with "srcElement is null". Reproducible while running the test via mutt or via mozmill. Fails more often under windows (~4-5 out of 10) OSX and Linux have lower failure rates (~1 out of 10)
Drag&drop might be important for metro automation. So we should think about getting it into 2.0.
Andrei, can you please check if this is fixed now?
I can't reproduce this anymore.
