I've built a component and embedded a Rich Text Editor in it. In preview mode the control works perfectly as intended - when I fill the control with text, a scrollbar appears and begins to scroll the text as more is added:

But once I publish the app, the interface begins to disappear as more text is typed:

No amount of erasing the text will bring the interface back.... these are the main settings on the control:

I most recently tried hard coding the height property to see if that fixed the issue, but it didn't.
I found someone with potentially the same issue, but no resolution was ever added. I'm wondering if anyone has an idea for why this is happening and if there's a way to fix it.
My app design is responsive (aspect ratio lock is off, scaling is off), which I fear may be the contributing factor into why this happening. Any suggestions or thoughts are welcome!
