Does it still have the limitation of SSE ie; it'll stop working after you open 6 tabs?

This limitation is gone with HTTP/2 and HTTP/3 and the Mercure hub automatically use the most recent protocol supported by the browser.

That is if the connection isn't downgraded by some other mechanism. Lots of corporate clients downgrade connections to HTTP/1.1 due to how their network is setup.

There is also an issue with SSE I've noticed that websockets doesn't seem to have as much of a prevalent issue with, and that is being blocked by corporate firewalls.

Most websites use TLS, HSTS and the like nowadays. It’s hard for a corporate proxy to downgrade the connection.

Also, the limitation is only applied by browsers, not by (reverse) proxies and other non-browsers clients.

That being said, Mercure allow to subscribe to many "topics" using a single HTTP connection. This helps mitigating the limitation with HTTP/1 (which is very uncommon these days).
