Pressing Ctrl+Z in an editor with unchanged content removes the content

[philiphendry]

If the editor is loaded and initialised with content then if, I give the editor focus and press Ctrl+Z, then the initial content is removed (presumably "undone" even though no changes were made.) This is confusing behaviour for a user if they have been making changes as they'll undo their own work but then see everything vanish.

Steps for Reproduction

1. Visit https://quilljs.com/playground/react or https://quilljs.com/playground/react
2. Step Two: give focus to the editor
3. Step Three: Press Ctrl+Z

Expected behavior:

The initial content of the editor should remain and not be removed when pressing Ctrl + Z.

Actual behavior:

The initial content is removed.

Platforms:

Windows 11 Version 23H2 (OS Build 22631.4460)
Firefox 133.0
Edge 131.0.2903.70

Version:

Run Quill.version to find out
2.0.3 (at the time of accessing the playground pages)

Maybe the example should have had a line added to it. In the Editor.js file try adding this: quill.history.clear(); just after the initial content is set.

It should look like this just after Quill is instantiated

if (defaultValueRef.current) {
  quill.setContents(defaultValueRef.current);
  quill.history.clear();
}
