Overriding Admin Block not Honoured - Defaults

[joshAntoniuk]

Describe the Bug

Adding an override for an Admin Component Block does not honour that change. For example, in the website template, if you edit a page, and add a layout (in this case, lets say a CTA), it by default shows the collapsible Admin Block which contains all the editable information. If you go to the CTA types, and add -
admin: { components: { Block { path: 'path/to/component#component } } }
Note: removing the path object, using jsx, or adding exportName do not fix this issue.

After generating the import-map and types, adding that CTA block still shows the default editable collapsible block. Hovering over the Block object, the type is defined as such: This will replace the entire block component, including the block header / collapsible.

Maybe my logic is wrong, but shouldn't that override?
