This is mostly caused by numerical precision being stressed, mainly just triggers some debug code to assert in Skia but otherwise doesn't have any harmful consequence, and is not otherwise easy to fix. Ideally we should handle this via the mechanism in bug 1305151 rather than trying to fix directly.
