Because I’ve got “Block third-party cookies” enabled by default, it seems to block access to `localStorage`

I’ve opened an issue at [codesandbox-client](https://github.com/CompuIves/codesandbox-client/issues/1392) and a quick browse through the code, it looks like there is a unused `InMemoryStore` that it could fall back to in this case.

Probably any online editor will fail to work without cookies enabled for their site. Not sure what can be done though. Will it work by just enabling InMemoryStore?

I didn’t realise that blocking third-party cookies also blocked third party `localStorage` access, but it looks like that is where all the errors are coming from.

The code has two implementations of `SyncKeyValueStore`, the [`LocalStorageStore`](https://github.com/CompuIves/codesandbox-client/blob/13c9eda9bfaa38dec6a1699e31233bee388857bc/standalone-packages/codesandbox-browserfs/src/backend/LocalStorage.ts) and [`InMemoryStore`](https://github.com/CompuIves/codesandbox-client/blob/13c9eda9bfaa38dec6a1699e31233bee388857bc/standalone-packages/codesandbox-browserfs/src/backend/InMemory.ts). However, now I look a bit deeper, it looks like there are [plenty of other usages of `localStorage`](https://github.com/CompuIves/codesandbox-client/search?q=localstorage.getitem&unscoped_q=localstorage.getitem) throughout that repository which it might be tripping up on.

I would need to debug a bundled version to get a better idea of where its actually breaking.

I think many of the errors are caused by the `debug` module which uses `localStorage` in the browser and has no fallback:

Looks like there is a fix:
