Rollup merge of #81716 - m-ou-se:fix-ice, r=eddyb

Fix non-existent-field ICE for generic fields.

I mentioned this ICE in a chat and it took about 3 milliseconds before `@eddyb` found the problem and said this change would fix it. :)

This also changes one the field types in the related test to one that triggered the ICE.

Fixes #81627.
Fixes #81672.
Fixes #81709.
