ChoiceField class
An interactive drop-down field whose value has Bangla shaped correctly.
Mirrors pw.ChoiceField. Only the field's appearance stream — what a
reader draws before the field is focused — is shaped here. Once a user
edits the field, the viewer re-renders it from the form font, which is
outside any PDF producer's control.
