field_A is validated. The problem is that when you submit the form without
selecting a value for field_A, the reloaded page including the form errors
initially hides field_A (including the error message below it). If you
change the value of field_B and then change it again to "Choice 2", you
will see field_A appear along with its error message.
Two things you probably want to do. First, assuming field_A isn't actually
required unless Choice 2 is selected in field_B, you should change the
field_A validator to IS_EMPTY_OR(IS_IN_SET(...)). Second, your Javascript
should check whether field_B already has a value of Choice 2 (e.g., if the
form is reloading with errors, and Choice 2 is already selected), and don't
hide field_A in that case.
