4 years ago
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36

Steps to reproduce:

Originally reported by one of our users here:  https://github.com/zeroclipboard/zeroclipboard/issues/282

Steps:
1. Enable Flash Player, if not already.
2. Navigate to:  http://rawgithub.com/koganei/ZeroClipboardIssue/master/index.html
3. Click and hold on any of the divs.  (You will actually end up clicking on a transparent Flash object.)
4. Drag that Flash object over the other divs.


Actual results:

The UI of the div that the Flash object was hovering over at the time of your click will sometimes be hijacked by the transparent Flash object, so that it almost looks like the items are being reordered and/or having their text changed as you drag (they're not).

Here's a video clip from our user:  http://www.youtube.com/watch?v=2hqq1dprJjE

I was also able to repro this last week on my box as well.


Expected results:

1. I'm no Flash expert but, AFAIK, Flash objects should not be draggable by default, so it's weird that this one appears to be.  I did not expect it to be draggable.
2. The Flash object should definitely NOT have assumed the underlying element's UI when dragged.

P.S. This is not reproducible in any non-Firefox browser.  Not sure if it was the case in older versions.
Hi reporter,

I haven't managed to reproduce this issue on the latest release(43.0.4) nor latest Nightly(46.0a1). Nothing strange happens when clicking and dragging the mouse over the divs, as seen in your video.

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20160105164030

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:46.0) Gecko/20100101 Firefox/46.0
Build ID: 20160107030235

Can you please try to reproduce this on the latest release(43.0.4) and latest Nightly(46.0a1) and provide the results? When doing this, please try to reproduce with a new clean Firefox profile, maybe even in safe mode, as some of this issues may be caused by third party installed add-ons or custom settings(https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems).

Thanks,
Paul.
