Uncaught (in promise) TypeError: This readable stream reader has been released and cannot be used to read from its previous owner stream

I see there's another 'Unhandled Promise' issue but this looks different. Not sure if it is in LDFlex or a dependency.

It is intermittent, but if you clone this repo and run yarn && yarn dev, then refresh the browser a dozen times you should hit the following in the TestLDFlex.svelte component:

I've also seen this issue intermittently in the Chrome browser when developing. Firefox seems unaffected and the built app runs in Chrome. A race condition?
