The cursor moves to the document header when setValue

[susan88323]

Describe the bug I am listening the onDidChangeModelContent event. When the content has been changed, I did some updates on the editor value and set the value e.g. editor.getModel().setValue(trimmedValue);. However, when the setValue is called, the cursor moves to the document header.

To Reproduce

editor.onDidChangeModelContent(() => {
      const curValue = editor.getModel().getValue() || "";
      if (curValue.length > maxLength) {
        const trimmedValue = curValue.substring(0, maxLength);
        editor.getModel().setValue(trimmedValue);
      }
    });

Expected behavior When setValue is called, the cursor should stay at the original position

Try use editor.getPosition()

const position = editor.getPosition()
editor.setValue(text)
editor.setPosition(position)
