preOnLoad event (or, advanced property for initial css properties)

bumping this, because the form i’m working on, today, looks kind-of silly when it loads.
the alternative, to have the component hidden via the visible css property, means it is also hidden in studio, when i am working on the form. it is just a matter of time before i forget that it is there, and do something regrettable to the form, as a result.
