websockets reconnect after element removed

After an element with a `ws-connect` attribute is removed, the socket connection is closed but then immediately reconnects. If a long lived web page adds and removes many elements with `ws-connect`, every websocket that ever lived still keeps reconnecting.

This behavior seems to have been added by [this commit](https://github.com/bigskysoftware/htmx-extensions/commit/e87e1c3d0bf728b4e43861c7459f3f937883eb99).

Start by reviewing the commit linked in the issue and trace the reconnect behavior for elements with a ws-connect attribute. Reproduce removing such an element, then verify that its socket closes without reconnecting and that repeatedly adding and removing elements does not leave old connections active.
