I don't really worry much about minor players in the android-epub-reader-du-jour game. They come and go like the weather.
If there's quick and easy, non-intrusive, spec-compliant workarounds we can add to make more android readers happy, I'm all for it. But if they can't handle the very basics of how html is supposed to work, I'm not inclined to spend much energy helping their broken reading apps do what they should already know how to do.
