• Fix React warnings (and potential malfunction) when opening a recording
  in list view. FullScreenVideo was not wrapped in React.forwardRef,
  so MUI's Modal/FocusTrap could not attach a ref to it. Also fix
  an MUI warning about the modal content node not accepting focus, by
  adding tabIndex={-1} to FullScreenVideo's root element.
• Fix frequent intermittent live view failures in Firefox.
  Concurrent Blob.arrayBuffer() calls in the WebSocket message handler
  could resolve out of order, delivering fMP4 segments to the SourceBuffer
  with non-monotonic decode timestamps. Fix by processing messages
  sequentially via promise chaining.
  Fixes #343.
• Use real hyperlinks to issues in live view error alert.
  Fixes #326.
• Fix 9x16 videos being stretched to the full screen dimensions in
  list view full screen mode. Clean up some references to ancient
  Firefox versions along the way.
• Test and fix dir pool shutdown with multiple streams.
  v0.7.26 introduced a busy loop error in this case.
• Fix debug-mode panics within moonfire-nvr config command.
• Update to retina 0.4.17,
  which improves compatibility with several camera models.
