Mouse events on a pdf object should not be visible to container element

Project Member Reported by mustaq@chromium.org, Aug 18 2016 
0. Open the repro: http://output.jsbin.com/dufarop
1. Move/click mouse inside green box (the plugin) and also in-between green & grey boxes (parent div).
2. Mousedown on green, drag out to grey.
3. Mousedown on grey, drag into green.

Actual outcome: All mouse events on the pdf object are visible to the html.

Expected: Not sure which spec defines the expected behavior here, but the pdf object behaves clearly differently in both FF & Edge:
  [FF] All mouse events on the pdf object are invisible to the html. Same is true for drags /starting/ on the pdf object.
  [Edge] All mouse events on the pdf object are invisible to the html. A drag that stared in the object & moved out is visible as long as not over the object.

At the very least, we should hide the mouse events on plugins from the containing DOM element.

This came up in another conflicting bug: https://bugs.chromium.org/p/chromium/issues/detail?id=61574#c17

Summary: Mouse events on a pdf object should not be visible to container element (was: Mouse events on an object should not be visible to container element)
This is trickier that I thought: the behavior depends on object type!

For flash objects, Chrome, FF & Edge all pass on the mouse events to <object>. Repro: http://output.jsbin.com/luzasa

(The repro in the original post above is for a pdf object.)

Both Issue 61574 and  Issue 659670  seem conflicting with this bug, so I am inclined to mark this one as WAI.

The only question that still puzzles me is: why did both FF & Edge make the pdf object (hides the mouse events) different from flash (crbug.com/61574#c17)?
