Test and build failing because of issues with importing getRenderAccelerationFlyout from plugin.tsx. I think it's because running Jest tests doesn't start the plugin, which means the flyout doesn't get exported. I did a temporary fix for that in #1495 here.

Plugin.getRenderAccelerationDetailsFlyout = jest.fn();
