Hi Erik,
In your post, are you explaining what happened after creating your new case detail page, or were your observations referring to your existing pages?
We have tried to reproduce this behavior, but so far the rich text editor has behaved as expected for us. I suspect there’s something specific to your Lightning page that’s causing this trouble since the tests we ran didn’t reproduce any errors. Have you tried building a very simple page that uses only the components that are involved in the issue?
It sounds like a Queue may be involved- are you referring to a Skuid Queue component, or a Lightning component?
