Uncaught (in promise) TypeError

Hi,

When I try to run the browser example in Chrome, the Block Editor seems to work fine. But when I add some content I get an error in the console, and I have no idea how to fix it.

Uncaught (in promise) TypeError: Cannot destructure property 'name' of 'a[n]' as it is undefined.
at isolated-block-editor.js:2:1739804
at async t (isolated-block-editor.js:2:1746686)
at async o.elementResize (isolated-block-editor.js:2:1747879)

I have made no changes whatsoever. Just downloaded the code, and opened src/browser/index.html in a browser.

Start by opening src/browser/index.html in Chrome and reproducing the error after adding content. Inspect the reported failure in isolated-block-editor.js; done means the browser example accepts added content without the uncaught promise TypeError.
