Custom event filter not working, SyntaxError: missing ) in parenthetical

[Guilouf]

I have a list of item in a container, which has a trigger to be refreshed every 2 seconds. But, when a boostrap5 modal is opened from one the fetched item, i want to interrupt the polling.

<div
          hx-get="/item-list"
          hx-trigger="load, every 2s [show.bs.modal from:body]">
</div>

The event show.bs.modal from:body is working sandalone, but i can't get it to work as a conditional for the polling event, as it raises a syntax error:

SyntaxError: missing ) in parenthetical

I'm not sure if it's a bug or some misunderstanding from myself.
