Description

Started a thread on Discord and then was directed here: https://discord.com/channels/856971667393609759/1466175692575346698

I don't like that this usage of the beforeunload event is forced on me just because I choose to used Clerk. It creates a somewhat annoying UX if the user ever wants to use the browser navigation or refresh button, go through a redirect flow for an integration...or in some cases just navigating pages.

javascript/packages/clerk-js/src/core/auth/safeLock.ts

Lines 8 to 10 in 583f7a9

	window.addEventListener('beforeunload', async () => {
	await lock.releaseLock(key);
	});

At the very least, could you provide a config option to disable it?
