fix: remove unconditional external from vite build

[ricokahler]

Description

This one is just a quick follow up for #6394.

I merged @binoy14's PR to unblock another item i'm working on and I later found out that there was an unconditional thing that should've been deactivated. #6514 is a better fix but this should go in now. Apologies for any noise.
