All settings are lost when the Template contains the "%" character in the Workflow Definition

Issue

• I created a notification in a node of my Workflow and inside the Template field I placed a content that has the character "%", for example:

  <![CDATA[We received your shipment %]]>

• After saving and reopening the Workflow, all settings are lost.
• The following error appears in the DevTools Console:
  

  Uncaught (in promise) URIError: URI malformed
