Description

Fixes #14168

This PR resolves an issue where the Type field disappears from the "New Category" form after clicking the "Save" button without filling out other fields (e.g., Title, Description, Alias, and Color). The fix ensures that the Type field remains visible and persists regardless of form validation failures.

This change shows the field where it shouldn't now as the bundle is known when creating the category for example from the segment edit form, it's obvious that it should be for segments:

And please, cover the change with functional tests that will make sure it won't get broken in the future.
