Problem extending text field

[apademide]

Description

I'm trying to extend the text field but it appears to modify the markup and break the field: where the default text field uses <input>, the extended field uses <k-hello-input> making it unusable.
Reproducible with a 1:1 copy of https://getkirby.com/docs/reference/plugins/extensions/fields#extending-existing-fields

It appears to be very specific to the text field (number works, date works, textarea work; didn't test more advanced fields)

Using the exact field from the ref exemple above

text:
  type: text
  label: Text Field
hello:
  type: hello
  label: Hello Field

I don't think this is a v4 problem but already exists in v3.
The issue is that our text field automatically uses a k-TYPE-input, to automatically use k-url-input etc. when needed. So it's looking for a k-hello-input that does not exist.
