I'll worry about calibre book viewer handling embedded Javascript after it starts handling fixed layout epub3. Considering the issues with QT that have been reported such as QT 5.12.1 using a minimum 1 sec resolution, I'm not holding my breath waiting for either.
Out of curiosity, how are you handling the fallbacks for non-scripted renderers?
