Comment (by jonsurrell):

 > I confirmed that this issue still reproduces. However, it seems to occur
 in browsers other than Firefox as well. This might be a separate issue.

 I've been unable to reproduce this (on trunk at
 `ac539ca198ccef82c26d79a716cc22cf3750f240` which includes r62410).

 It's very surprising because we can see the module specifier in the
 importmap in the shared snippet: `"@wordpress/abilities":
 "…/abilities/index.js?ver=…"`.

 A possible explanation that comes to mind is the context. In the editor-
 canvas iframe, the module is unlikely to be available (see #64360). The
 `@wordpress/abilities` module should be available to import in the top
 context where the importmap is included. If I change the context to the
 site-editor iframe or try to use it in a script in that context I see the
 same errors.
