Maybe duplicate ones. But it would mean that e.g. incorrect ones (too
long duration) would be impossible to get rid of for example.
It also means that seeking is not reproducible (the result of seeking
would always depend on what you played before).
I admit that it is probably to a large degree an artifact of libass
probably not handling it well at some point and might no longer
be truly appropriate, but I do kind of appreciate the reproducible
behaviour aspect at least.
