[BUG] Swapping elements via websocket doesn't trigger transitions

Sending `

` over a websocket does not trigger the transition. If, however, you perform a hx-get request and perform oob-swap with the exact same HTML swap it does show the transition.

I had a look through both the WebSocket extension and the base HTMX library but as I'm no expert in JavaScript i couldn't find anything.

Using HTMX: https://unpkg.com/htmx.org@2.0.1
Using websocket extension: https://unpkg.com/htmx.org@1.9.12/dist/ext/ws.js

Doesn't matter if I use "hx-swap" attribute to set a transition either. Tested on both Firefox and Chromium.

Reproduce the difference between the hx-get out-of-band swap and the websocket swap using the versions in the report. Start with the websocket extension entry point at dist/ext/ws.js and compare its swap path with the base HTMX transition handling. Done means the identical hx-swap-oob HTML sent over websocket triggers the transition in Firefox and Chromium.
