IE: drag thumb on scrollbar in sortable item tries to drag sortable item

[Ed]

My sortable items sometimes have scrollbars. On Chrome, this works fine, but on IE, I have issues.

On a sortable item with a scrollbar, click on the thumb and drag it to move the scrollbar, when you do a mouseup, the drag event of the sortable continues and won't release until I press the esc key.

I am currently using IE9 (9.0.8112.16421)

Thanks,

Hi Ed,

Is it possible for you to provide a small but runnable example which demonstrates the scenario? In this way I will be able to examine your exact case in details and assist you further.

Hi Alexander,

I've created a jsFiddle for you. Let me know if you can repro the issue. Click (mouse down) on the scrollbar thumb to scroll down then move outside the <li> element and mouse up. What you should see is: as soon as you mouse up, the <li> element will be attached to the cursor and won't let go (with fingers off the mouse buttons at this point) until you click the ESC key.

Hi Ed,

thank you for contacting us. This seems like a variation of a known issue, which, unfortunately, we haven't figured out how to fix.

Hi Petyo,

FYI, this is on IE9 too. We no longer support IE8 on our site, but IE9 and above is supported. This issue happens with IE9.  Please update bug to reflect that too. Perhaps that info too, will help isolate the issue.

Thanks,

Also, if it were only IE8, I would agree that Sev:Low is appropriate, but since it is also IE9, I would like the Sev to me bumped up a bit.

Thanks,

Hi Ed,

thank you for your feedback - I noticed that you commented in the issue, too. Unfortunately, the addition of IE 9 does not help much in the resolving of the issue - we haven't figured out how to detect clicks on the scroller, apart from the very crude and error-prone pixel measuring. If we do this, it may affect our performance seriously.

Hi Petyo,

Thanks for the update.

Have you opened a ticket with MS regarding this and asked them what the issue is - if it is a recognized bug in IE and if they plan on patching it and/or in what version of IE has it been resolved?

This is an important one for us and we request you to open a ticket with MS if not already done. If necessary, we can open a ticket with you and/or MS to help move the process forward.

Hi,

given our experience with the IE team and their (lack of) bug report responsiveness, especially when it comes to old IE versions, we don't consider such action necessary. In addition to that, the issue does not manifest in newer IE versions (10, 11).
