Comment (by Chouby):

 The usages I remember having seen for `switch_to_locale()` are for sending
 emails, creating documents such as PDF invoices and displaying the admin
 bar in a different language than the main language on frontend.

 I don't foresee a usage which wpuld require to switch the locale before
 displaying the backend of widgets.

 However, if we want to be on the safe side, then it would indeed be
 necessary to reset the static variables on `change_locale`.
