Drag&drop-reordering of columns broken in Firefox 63 and Internet Explorer 11

Reordering columns in the Alarm Table through drag&drop only seems to work in Chrome, out of the three browsers I have tested.

In Firefox 63 (tested on Windows and Linux), the following error is printed in the JavaScript console:

TypeError: evt.path is undefined[Learn More] vendor.d1f313cb0bbe86ea2d5f.js line 235 > eval:144:24
getTarget
editor.js:42:4
handleEvent
editor.js:54:19
_loop/<
editor.js:28:44

In Internet Explorer 11 (which I just tested out of curiosity), the following error is printed instead:

SCRIPT5007: Unable to get property 'Symbol(Symbol.iterator)_9.jiia7s6a82a' of undefined or null reference
File: editor.js, Line: 162, Column: 19
