Description
Via code inspection, we have identified that there is a potential bug in
DEFAULT_BUFFER_TIME_JITTER_FRACTION. Specifically, if the fraction happens to be set to 1.0, we end up not respecting the buffer time for cache refresh (see diagrams in #2335). This PR will cap the max fraction value to 0.5 to avoid the problem.Checklist
