steimel@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

This is related to my change, but what's happening is that the fuzzer is using internals to change the ids of elements inside the shadow dom, causing us to not find the track element by ID here: https://cs.chromium.org/chromium/src/third_party/blink/renderer/modules/media_controls/elements/media_control_slider_element.cc?l=96

Since this isn't actually something that can happen without using internals, I'm closing this as WontFix. Thanks!
