Description
A recent change #3336 that just shipped in 2.0.5 has introduced a regression bug where if links contain elements trigger click events it now uses the contained element instead of the wrapping link to make the decision of if the click should prevent a links default navigation behavior. The fix that broke it was designed to handle situations where you listen for a click event on a higher up element causes checkboxes and other elements to lose their ability to operate with clicks if the active htmx element is a form or a link. And to fix this issue it now checks the element that was clicked for if it is a link to prevent instead of the active htmx element.
To fix this issue i've added a line to the shouldCancel link checking code to located the closest wrapping link (or the event element itself if its a link)
Also found another edge case issue this resolves that is not working in older htmx versions as well. If you place htmx attributes on an element like a button and wrap this in a link for progressive enhancment the link would still get triggered unless you move all the htmx attributes up to the link tag instead.
