That orientation used to be referred to as Super-Gay (Super-Straight is when you're only attracted to biological members of the opposite sex).
The super-\w* orientations aren't real. It would require being able to reliably distinguish between cis and trans people of the same gender at a glance, which isn't possible. Attraction isn't based on sex, or even gender identity, but on gender presentation. A lesbian can be attracted to someone of any gender identity if they have a feminine gender presentation (that appeals to her), and it doesn't make her bisexual if that person is a man. It's not about who she's willing to have a relationship with, it's about who is hot to her on a base, emotional level.
Oh man, it's the sexual orientation police. Hide the sapio-sexuals, everybody!
