Wouldn't it have been quicker just to try it?

Although I don't know the answer, I will point out that transparency has
always been a tricky issue with PostScript and, by extension, PDF.  Both
standards were designed with paper and printing in mind, where
transparency does not exist.  Most professional print shops will not
accept PDF files with embedded transparency, because it's not clear what
that means.
