fix: Fire htmx:trigger event on delayed triggers

[WKBae]

Description

hx-trigger with delay modifier did not fire htmx:trigger event. This behavior was inconsistent with plain(non-delay) events.
Demo: https://jsfiddle.net/yu59noed/

Testing

Added test case for delayed htmx:trigger. This test case failed on current dev branch.

Hi @WKBae I just found the same inconsistency and found your fix for that is already in the pipeline! Good work! However it seems your fix could also cover the throttle modifier as looking at the code, few lines above your fix, it seems it suffers from same omission.

Thanks in any case! :)

good fix, please retarget to dev

@1cg Oh I forgot to change it. Thanks for the reminder!
