Can't dynamically change source HTML "on the fly"

[jaybo]

I need to dynamically reload the HTML tree in response to an outside event (clicking on a map icon).

Usually this works fine, but Intermittently (maybe only if there is image content?) I get the dreaded:

Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. 
Instead, use a data or computed property based on the prop's value. 
Prop being mutated: "node" VueComponent {_uid: 392, _isVue: true, $options: {…}, _ …} 

found in

---> <OEmbed>
       <EditorContent>
         <QuasarTiptap>
           <QItem>
...

or:

...Prop being mutated: "node" VueComponent {_uid: 620, _isVue: true, $options: {…}, …} 

found in

---> <OImageView>
       <EditorContent>
...

After numerous fumbled attempts, I'm coming to the belief that I can't fix this on my end.
Could it possibly be resolved by inserting cleanContent() at the very beginning of setContent() within quasar-tiptap?
