Logic insert signature with quote incorrect

[dab246]

Issue

Cannot insert signature with quote

message: NotFoundError: The object can not be found here.

Root cause

This is a DOMException that usually occurs when trying to insertBefore() a node before a node that is no longer in the DOM or is not a direct child of the parent that is calling insertBefore on.

The statement causing the error: nodeEditor.insertBefore(signatureContainer, quotedMessage);. quotedMessage is not a direct child of nodeEditor, will throw NotFoundError

Solution

Check parentNode === nodeEditor before call insertBefore to avoid this error.
