Websockets extension not working in Safari

[artemgordinskiy]

Using HTMX v1.9.10 with the latest ws.js on Safari 17.4, I am unable to establish a websocket connection.
This works in every other browser I've tried it in.

Here is a reduced test case:

<div hx-ext="ws" ws-connect="wss://echo.websocket.org">

Error trace from Safari:

[Error] TypeError: null is not an object (evaluating 'elt.hasAttribute')

I was also able to reproduce the issue with this test project:
https://github.com/chuhlomin/htmx-websockets

Has anyone else encountered this issue before?

There seems to be a fix for this in #2391

У меня аналогичная проблема, некоторые устройства на iOS Safari работают, а некоторые нет. в других браузерах все работает.
не работает на 17.4 , а на других работает
