Ionic Framework Version

v8.x

Current Behavior

On iOS, if you add ion-menu with swipe-gesture enabled on a page, and then navigate to a different page, and swipe from left side of screen to the right, there is a javascript error:

TypeError The provided value is non-finite 

Here is stacktrace:

    f://localhost/assets/p-CtukzcyX-BJW7t2Im.js:2:2217 
    [native code] forEach
    f://localhost/assets/p-CtukzcyX-BJW7t2Im.js:2:2210 Q
    f://localhost/assets/p-CtukzcyX-BJW7t2Im.js:2:5030 progressStep
    f://localhost/assets/p-CtukzcyX-BJW7t2Im.js:2:5022 
    [native code] forEach
    f://localhost/assets/p-CtukzcyX-BJW7t2Im.js:2:5002 progressStep
    f://localhost/assets/smartRouter-CIhTEPpS.js:2:463597 onMove

It seems to come from the code:

const step = deltaX / this.width; // deltaX / 0 = NaN
this.animation.progressStep(NaN); // throws "The provided value is non-finite"

This could be due to swipe using a full document listener, but menu has 0 width since it's not currently rendered.

Expected Behavior

No error

Steps to Reproduce

See above.

	const stepValue = delta / this.width;
