Converting a Group to a Frame is broken?

When editing a master component, using the UI pulldown menu (right sidebar inspector) to convert a Group to a Frame updates the layer display, but the underlying Plugin API node type incorrectly remains GROUP instead of changing to FRAME.

The issue here is that there’s now a mismatch between the way the API can access this node type and the way it’s represented to humans in the display tree; Humans can’t visually verify that we’re looking at a false Frame (that’s really just a Group) unless they run dev console commands against the node type.

Steps to reproduce: 

1. Create a Component
2. Add random things to it, Group those items
3. Select the Group
4. Type this in the console:
   1. console.log(figma.currentPage.selection[0]?.type);

   2. ​​​​​​Note that it says “GROUP”

5. Use the UI to switch in the sidebar to change it into a Frame

6. Repeat the console command

7. Note that it still outputs “GROUP”, and display tree says that it’s a Frame
