### Beta/Release Uplift Approval Request * **User impact if declined**: youtube video would stuck on infinite buffering on certain situations * **Is this code covered by automated tests?**: Yes * **Has the fix been verified in Nightly?**: No * **Needs manual test from QE?**: Yes * **If yes, steps to reproduce**: Follow the steps 1-4 in bug 1904937 comment 0, then perform seeking to random position multiple times to ensure the video playback is smooth without having infinite buffering. * **List of other uplifts needed**: no * **Risk to taking this patch**: Low * **Why is the change risky/not risky? (and alternatives if risky)**: This patch improves the eviction algorithm we use for MSE, which will only be used when buffer full and the targeted data isn't in the buffered range. So it won't affect most of playback situations where the buffer is still not full. If the buffer is already full, not having the data evicted would result in even worse situation, where youtube player has a problem to handle that case. * **String changes made/needed**: No * **Is Android affected?**: Unknown
