Initial content is open for undoing (getting empty on undo)

[vintprox]

Vue.js version and component version

• vue version 2.6.11
• vue-codemirror version 4.0.6

Steps to reproduce

1. Make editor with model set: <codemirror v-model="draft" />
2. Initially set model: draft: 'TO WHATEVER TEXT'.
3. Open editor, press Ctrl + Z.

What is Expected?

Nothing must happen.

What is actually happening?

Content is cleared completely, and as I suspect because of behavior described here.

Would be plesant if first content was fed to editor at initialization call rather than at runtime.

Just have found a workaround! Issue can be negotiated with clearing history on load.

1. Bind event listener <codemirror @ready="onCmReady"... />.
2. Add method that clears history:

onCmReady(cm) {
  cm.doc.clearHistory();
  cm.refresh();
}
