[Bug]: Loading forever - MetaMask cannot start after blocking and unblocking request. Closing opening browser doesn't work but clicking Re-start works

Nobody has claimed this yet.

### Describe the bug

I found a way to reproduce the loading spinner/cannot start MetaMask and cannot recover from that state when closing opening the browser.

If you block on of the initial script requests (ie `use-snow.js`), the wallet cannot start (expected)
But then, if you unblock that, and try again, the wallet cannot start. Then if you close on re-open the browser, we see the same result.

I've seen that if I wait until the Restart screen and click that, still nothing happens, but at the second trial, the wallet then recovers (the request is sent).

I'm not sure how (if) the first case can be achieved without manually blocking the request (maybe some slowness into the computer)? and then this causing the infinite spinner issue for some users. (Those in which clicking the Reload button works)

Start by reproducing the sequence in the issue: block the `snow.js` request, restart MetaMask, unblock it, and retry across a browser restart. The issue provides no source files, tests, logs, or entry point; done means the extension recovers reliably after the request is unblocked and Reload/Restart is used.
