Confirm with the specification when generating emtpy option for select with `include_blank: true` option.

We now generate option with empty label, example:

`<select id="places" name="places"><option value="" label=" "></option></select>`

 for include_blank: true. This is only done, if content is missing on the option, and we providing the value from this option.

 Fixes #24816
