Fixed #1959 by postponing ALL script evaluations till the html insertion is done. Before the code would immediately execute any scripts that weren't in subelements if no subelements prior had scripts in them (i.e. once any script was postponed they all were). This could cause inconsistent behavior. Since, at this time, we have to postpone some scripts it makes more sense to postpone them all.
