This is actually extremely common. It's all over the dating app profiles of every transwoman. They love "dyke" probably for the same reason transmen love the f-word. Curiously they also all love making up stories where they claim they were called this by a stranger. I have never seen any transwoman IRL or anywhere online look anything like someone who would get called "dyke" by a stranger because absolutely no one would have think they're a homosexual female, but at best a cross-dressing male who wants to be seen as a woman. My girlfriend was aggressively called "dyke" by a stranger within the last few months while she was minding her own business because she's female but presents masculinely, so it is very much still being used as a slur against masculine women who are presumed to be lesbians (which she is).

In contrast, I fully believe transwomen of any sexual orientation get called the f-word because the vast majority are obviously male and are presumed to be homosexual. If you ask around, most people assume that Caitlyn Jenner was/is a closet homosexual male. It doesn't help that he is in that weird "non-relationship" with a fellow, but much younger transwoman that is his youngest kids' age. But it doesn't mean that trans women get to reclaim the f-word if they're not homosexual males or they are trying to identify out of being homosexual males.
