Steps to Reproduce:
- Edit an article using VisualEditor.
- Drag and drop an //existing// reference.
Actual Results:
- The reference disappears, throwing the below error in the console.
Expected Results:
- The reference is moved to the new spot.
This happens after [[ https://www.mediawiki.org/wiki/MediaWiki_1.34/wmf.24 | 1.34.0-wmf.24 ]], and only with an existing reference: a newly created one can be dragged just fine. As a workaround, cutting and pasting a reference still works.
