Inline form errors repeated on child elements

Is this a duplicate of ✨ Add a #disable_inline_form_errors_summary property to disable the Inline Form Errors summary Needs work ?

@cilefen No, its not duplicate.
Disabling inline form errors is not a solution, but an alternative.

The proper solution is to prevent repeating of error message on child elements.

ok

We shouldn't add the "Accessibility" tag unless this needs specific review from that team. Perhaps it does. Yet this seems an ordinary bug.

I've removed other tags according to https://www.drupal.org/node/3156530 → .

Tagging for sub-maintainer and usability as that may be by design. Following the steps you're adding a single reference field. If there are any errors in the form that field failed as a whole.

But will say think ✨ Add a #disable_inline_form_errors_summary property to disable the Inline Form Errors summary Needs work would be worth pushing along.
