[feature]: useScrollLock doesn't have an option to reset on unmount

[MichaelHeinzman]

Is your feature request related to a problem? Please describe. I'm utilizing the Dialog component with venia-ui to display a loading modal on the screen for the user after placing an order. However the dialog uses useScrollLock and it sets the scroll lock to true when the modal is open. We navigate away from the page when the modal is displayed so I think that causes the useScrollLock to stay activated.

Describe the solution you'd like On unmount, I would like useScrollLock to set the scroll lock to false, in cases where the modal doesn't have time to have it's isOpen updated.

export const useScrollLock = locked => {
    useLayoutEffect(() => {
        if (!globalThis.document) return;

        document.documentElement.dataset.scrollLock = locked || '';
        
        return () => {
          // Logic to set to false on unmount
          document.documentElement.dataset.scrollLock = false; 
        }
    }, [locked]);
};

Describe alternatives you've considered I would say our problem is in our use case, so setting the scroll lock to false before we navigate away would be ideal, it's just I was thinking this should be apart of the hook itself.

It could be this was already implemented, since we are using an older version of venia-ui.

Please let us know what packages this feature is in regards to:

• [8.0.0 ] venia-ui
• [ 12.5.1] peregrine
