Rather than Broadcast Channel, you can use the Web Locks API (https://developer.mozilla.org/en-US/docs/Web/API/Web_Locks_A...). This handles the leader election pretty seamlessly because all tabs try to become the leader and only one actually can. This library (https://github.com/pubkey/broadcast-channel) from the fantastic RxDB javascript DB library uses WebLocks with a fallback to Broadcast Channel. But, WebLocks are supported on 96% of browsers, so probably safe to just use it exclusively now

Yeah, the issue with SharedWorkers is that Android Chromium doesn't support it yet. https://issues.chromium.org/issues/40290702 But rather than Broadcast Channel, you can also use the Web Locks API (https://developer.mozilla.org/en-US/docs/Web/API/Web_Locks_A...) rather than Broadcast Channel This library (https://github.com/pubkey/broadcast-channel/blob/master/src/...) from the fantastic RxDB javascript DB library uses WebLocks with a fallback to Broadcast Channel.
