The old code kept track of this handler and would remove it in the workspace's dispose() function. Do we need to do something equivalent in the new code?

You are right. I added logic for disconnecting the observer

const resizeObserver = new ResizeObserver(() => {
Blockly.hideChaffOnResize(true);
Blockly.svgResize(mainWorkspace);
});

resizeObserver.observe(container);

Blockly.inject.bindDocumentEvents_();
