[htmx 4] Click events on elements with hx-get fail to trigger on iOS 15 Mobile Safari

Click/tap events on elements with hx-get fail to fire when opened in Mobile Safari on iOS 15 when using htmx 4. Downgrading the library to htmx 2 immediately resolves the issue without any changes to the HTML/CSS codebase.

To Reproduce Steps to reproduce the behavior:

1. Create a simple button element with hx-get, hx-target, and hx-swap attributes:

<button type="button" 
        hx-get="/api/v1/schedule?offset=-1" 
        hx-target="#schedule-grid" 
        hx-swap="outerHTML" 
        hx-push-url="true">
    ← Previous
</button>

1. Load the page on an iPhone running iOS 15 Mobile Safari
2. Tap the button.

Expected behavior htmx should intercept the tap event, issue an asynchronous GET request to the specified endpoint, and swap the target DOM node (#schedule-grid)

Actual behavior Nothing happens upon tapping the button. No network request is initiated in the browser developer tools console

Environment: htmx version: htmx 4 Device: iPhone
OS: iOS 15
Browser: Mobile Safari
Server Stack: Server-Side Rendering

Additional context Replacing the script tag source from htmx 4 back to htmx 2.x instantly fixes the problem on the exact same device and markup, allowing touch events to trigger AJAX requests as expected
