    [tools] Speed up system-analyzer · abf87441
    Camillo Bruni authored
    - Reuse DOM nodes if possible
    - Delay slow DOM node removal to not block the UI
    - Fix global time range syncing when adding timelines to the state
    - Use a Proxy to cache CSS colors instead of querying CSS properties
      on every access
    - Set className on newly create DOM nodes instead of adding to the
      classList
    - Use bound functions for event handlers that are added multiple times
    - Speed up Chunk.getBreackdown
    - Use CSS gradient for timeline-track chunk backgrounds, which is an
      order of magnitude faster than the serialised canvas approach
