Nextjs - Firefox can’t establish a connection to the server at ws://127.0.0.1:1234/.

Hi, there is an issue using slate-yjs in next@13.4.6. When I try to connect with HocusPocusProvider to my hocus-pocus server the socket connects and disconnects immediately. The connection reach the server but somehow the socket hangs up.

The problem is that for the same code, it's working without any problem with vite but not on nextjs.

Here is the link to reproduce the bug: https://codesandbox.io/p/github/pierrelouisdelx/slate-yjs-next/main?layout=%257B%2522sidebarPanel%2522%253A%2522EXPLORER%2522%252C%2522rootPanelGroup%2522%253A%257B%2522direction%2522%253A%2522horizontal%2522%252C%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522id%2522%253A%2522ROOT_LAYOUT%2522%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522direction%2522%253A%2522horizontal%2522%252C%2522id%2522%253A%2522EDITOR%2522%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL%2522%252C%2522panelType%2522%253A%2522TABS%2522%252C%2522id%2522%253A%2522clj6visrd000b3b6239wpwhoy%2522%257D%255D%252C%2522sizes%2522%253A%255B100%255D%257D%252C%257B%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522direction%2522%253A%2522horizontal%2522%252C%2522id%2522%253A%2522DEVTOOLS%2522%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL%2522%252C%2522panelType%2522%253A%2522TABS%2522%252C%2522id%2522%253A%2522clj6visrd000d3b620rccr33b%2522%257D%255D%252C%2522sizes%2522%253A%255B100%255D%257D%255D%252C%2522sizes%2522%253A%255B50%252C50%255D%257D%252C%2522tabbedPanels%2522%253A%257B%2522clj6visrd000b3b6239wpwhoy%2522%253A%257B%2522id%2522%253A%2522clj6visrd000b3b6239wpwhoy%2522%252C%2522activeTabId%2522%253A%2522clj6vnwau00ha3b62y8gh3hl2%2522%252C%2522tabs%2522%253A%255B%257B%2522id%2522%253A%2522clj6visrd000a3b62w5cdh252%2522%252C%2522mode%2522%253A%2522permanent%2522%252C%2522type%2522%253A%2522FILE%2522%252C%2522filepath%2522%253A%2522%252FREADME.md%2522%252C%2522state%2522%253A%2522IDLE%2522%257D%252C%257B%2522type%2522%253A%2522FILE%2522%252C%2522filepath%2522%253A%2522%252Fpackage.json%2522%252C%2522id%2522%253A%2522clj6vnwau00ha3b62y8gh3hl2%2522%252C%2522mode%2522%253A%2522temporary%2522%252C%2522state%2522%253A%2522IDLE%2522%257D%255D%257D%252C%2522clj6visrd000d3b620rccr33b%2522%253A%257B%2522id%2522%253A%2522clj6visrd000d3b620rccr33b%2522%252C%2522activeTabId%2522%253A%2522clj6vnj6l008r3b628ulv16z0%2522%252C%2522tabs%2522%253A%255B%257B%2522id%2522%253A%2522clj6vnj6l008r3b628ulv16z0%2522%252C%2522mode%2522%253A%2522permanent%2522%252C%2522type%2522%253A%2522TASK_LOG%2522%252C%2522taskId%2522%253A%2522dev%2522%257D%252C%257B%2522type%2522%253A%2522TASK_PORT%2522%252C%2522taskId%2522%253A%2522dev%2522%252C%2522port%2522%253A3000%252C%2522id%2522%253A%2522clj6vpvr400cm3b62q1y4mx1d%2522%252C%2522mode%2522%253A%2522permanent%2522%252C%2522path%2522%253A%2522%252F%2522%257D%255D%257D%257D%252C%2522showDevtools%2522%253Atrue%252C%2522showSidebar%2522%253Atrue%252C%2522sidebarPanelSize%2522%253A15%257D

Sounds more of an issue with hocuspocus, could you open an issue there? (https://github.com/ueberdosis/hocuspocus)
