"refresh" switches to "multiple" mode
picker.selectpicker("refresh") switches the component to multi-selection despite "multiple" not being defined on the original <select> element.
This seems to be an additional problem to issue #2738 Options and selection are duplicated

It seems development of this awesome library has come to a halt. See https://github.com/snapappointments/bootstrap-select/issues/2228#issuecomment-1236207188 I've reluctantly switched to https://github.com/select2/select2 I found after some research is one of the only libs to still show some development and is able to do what bootstrap-select did.
