html drag and drop does not work when there's a todo editor

[gfrancine]

Repro:

• Open a folder
• Create a new todo editor
• Add an item
• Drag a file tree item around

react-sortly depends on react-dnd, which hijacks all drag and drop events. There's a rootElement option, but it can't have multiple DnD backends and roots. Setting rootElement to the editor module's element would disable drag and drop on other editors. The ideal solution is to find an alternative to react-sortly.
