Dragged text disappears with no undo (potential for data loss)

[therealpygon]

Dragging a block of selected text from within a note and dropping it onto another note in the note list causes the text to disappear; cannot "undo" the removal of text.

Data is completely lost if cloud-sync and auto-save are enabled, as the file will save and sync immediately.

Environment

Joplin version: 1.0.216
Platform: Windows
OS specifics: 10 Pro

Steps to reproduce

1. Inside a notebook, create a note (source) and enter some text
2. Create a second note (target)
3. Select the text in source, drag the selected text onto the target note

Describe what you expected to happen

Dragged text should "move" from the source note to the end of the target note, just like dragging a note to another notebook will "move" the note.

Logfile

No relevant information in the logfile; simply shows the note had data, then was empty:
