Nesting Modal Frames

If you have a table, which opens a Modal Frame, that contains another table, should you be able to add another layer of Modal Frames?

In my current app, I am unable to drag a new Modal Frame into the existing Modal Frame. I'm trying to avoid using the legacy modals.

Should this be possible? Anyone else experiencing this?

Looks like you can add additional Modal Frames in the component tree, just make sure to disable the "close when clicking outside" checkbox. I still think this is unintentional UX, but it works for now.
