ts-type-error uses Vue 3.0.8. works uses Vue 3.0.7. The two projects are otherwise identical.

works builds correctly and runs correctly.

ts-type-error fails to build with the following error:

ERROR in src/App.vue:36:15
TS2345: Argument of type '{ readonly bar: string; log: () => void; }' is not assignable to parameter of type 'Foo'.
  Property 'baz' is missing in type '{ readonly bar: string; log: () => void; }' but required in type 'Foo'.
