Saving node form that fails validation results in no unlock button or message

Am able to replicate the issue. Would assume using $form_state->hasAnyErrors() would work but $form_state is showing no errors even when there are.

I've rebased this with HEAD; but I haven't been able to reproduce this with HEAD.

I could reproduce the problem with a field with custom validation (OP says one without HTML required support, e.g a text long, but text log have required support now?).

Also, the problem happens only with JS-enabled locking, so modified STR.

@smurtgrave You said you reproduced it, could you add concrete steps to reproduce?
I could too, but only when having a custom field with custom validation, which is probably a lot of work and overkill for a test here. Maybe your STR are more simple?

Not directly in front of my computer but I reproduced it with a media reference field.
