Cannot require a field with an alt-datetime widget

[samath117]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

core

Version

5.x

Current Behavior

Consider the form at this shared playground link.

A timestamp with the alt-datetime widget is placed in two layers of objects. It is required at the lower layer, but it is possible to submit the form without filling it in:

Expected Behavior

There are a couple similar / simpler cases that work correctly:

• Only one layer of objects
  
• Using the regular datetime widget
  
• Requiring the middle layer as well
  

Steps To Reproduce

@samath117 It's expected that if object_with_timestamp is not required, then you can submit it without filling out the field. The validation with the regular datetime widget is HTML5/browser validation, which is not controlled by RJSF other than globally enabling/disabling it, which is why you see different behavior.

Ah, apologies, I was missing another variant: With the default text widget, the behavior is the same as the datetime widget:
Object with String Variant

That is, there is no need to also require the intermediate layer in the normal text widget. The select and radio widgets (when the string has an enum) also have the same behavior. So the bug either lies with all other widgets or with the alt-datetime widget alone.
