I think it's working as intended, but I wonder if it can create UX issues.
It's definitely frustrating to me, but not forcing touch simulation might be more problematic?

It depends on what use case we want to prioritize:

• "I disabled touch simulation, and I expect it to stay off until I choose to turn it on"
• "I selected iPhone 6/7/8, of course I expect it to behave like an iPhone!"

I'm okay with a WONTFIX if we think the current behavior is the better trade-off.

Micah: I wonder if by disabling touch with a device selected it should change the selected item back to “Responsive”.

That could be a good option, I like it.
