At the very first appendBuffer() there are not tracks parsed yet, so platformMaximumBufferSize() returns 0 (as no tracks are there), and the limit is taken from MediaElementSession as audio limit 15MB as no video track is present. A potential buffer overflow at the very first appendBuffer() before tracks are parsed from init segment should be ignored.
