- Caused by feat: Add ResizeObserver to Grid and Chart #1626
- The children on IrisGrid were getting re-rendered as a result of IrisGrid.handleViewChanged getting called after updating the canvas in Grid.componentDidUpdate
- Another fix would be to memoize metrics and not emit a view change if they are exactly the same as previous metrics, but thought that was a bigger change (need to deep equals a bunch of maps and arrays in the metrics)
- Tested by opening up a table with React dev tools highlighting re-renders. Table did not re-render when not being interacted with.
