[Feat]: sp-number-field repopulate field after deletion

Impacted component(s)

sp-number-field

Description of the requested feature

Currently, removing the number in the number field leaves the number field blank. It would be nice if the number field could repopulate to either the previous value, or the default value (ex. 0).

0 and undefined are highly different values both in javascript as well as within the context of a working application. Where there to be a "default after deleting" how would you expect a user to inform the application that undefined was the correct value?
