The subscript and superscript won't go under and above the symbol.
Is there a way to make this work?
I don't know, but there has to be since superscripts for some symbols are interpreted as "script above".
In any case, this motivates the workaround, which should provide reasonably good results in your case (union/intersection/etc), of using Insert->Script->Script above (or the corresponding shortcut, ctrl+A in my setup).
Best,
