Bug description

Trying to drag a task in Chrome, Edge or Vivaldi crashes browser window. Dragging works in Firefox, though. Tried on 3 different Windows computers. Problem exists on both NextCloud 27.1.3 on self-hosted, manually installed Ubuntu 20.04 server and 29.0.7 on an up-to-date Cloudron server. All plugins are updated.

I cleared my browser cache and cookies. Closed everything, restarted my computer.
I cleared some disk space on my Cloudron server and increased the memory available to the app.
I stopped and restarted the Cloudron container as well as both the servers.

Steps to reproduce

1. Open Tasks and create a task and subtask.
2. Drag subtask.
3. Watch browser window crash and throw "Error code: RESULT_CODE_KILLED_BAD_MESSAGE"

Expected behavior

Dragging and dropping.
