Errors not showing in FieldErrors when field name contains a dot.

[f-elix]

Describe the bug

I had some field names containing a dot (e.g. 'selected.days') and errors for the field wouldn't show up with the FieldErrors component, even though there were in the $errors superform store. Took me a while to figure out that this was the problem. If you look at the reproduction, you can see that the errors for 'selected.days' don't show up while those for 'selected_days' do.

Not a huge problem, just thought you would like to know.
