Unable to drop up on Firefox on Linux

[aurelien-reeves]

Hi,

I have just notice a weird behavior on Firefox (nightly, and 59.02) on Linux (Mint 18/ Cinnamon).
It can be noticed here: http://mharris717.github.io/ember-drag-drop/#/sort

It is possible to drag and drop elements down, but when trying to drag and drop elements up it is not possible to drop them more than one element up.

It is working fine on other browsers, and on Firefox on Windows and on Mac.
Other drag&drop libraries do not have that issue like jquery: https://jqueryui.com/sortable/

Note: nothing in the browser console. No error, nothing.

Same issue observed here, using Firefox 62.0 on Ubuntu 18.04. In Chrome 64.0 it works for me.

The library does not use jquery any more as of 0.6.0. Maybe give that version a try?

Same issue with version 0.6.2, using Firefox 62 on OpenSuse.

Update: I have updated my system same problem on Firefox 64.0.

Not an issue for me anymore when using ember-drag-drop v0.6.3. 👍
