WKWebView - prevent automatic scrolling triggered by user text selection

Question

When a user performs a tap and hold gesture to select a word and then drags their finger towards either the top or bottom edges of the screen, the page automatically scrolls

Answer 1

I ended up solving this problem by saving the last scroll position and scrolling to it when appropriate, like so:

var shouldAllowScrolling = true;
var lastSavedScrollLeft = 0;
var lastSavedScrollTop = 0;

function saveScrollPosition() {
    lastSavedScrollLeft = window.pageXOffset || document.documentElement.scrollLeft;
    lastSavedScrollTop = window.pageYOffset || document.documentElement.scrollTop;
}

document.addEventListener('touchstart', e => {
    saveScrollPosition();
});

document.addEventListener('touchend', () => {
    // enable scrolling when the user lifts their finger, to allow scrolling while text selection is still present
    shouldAllowScrolling = true;
});

document.addEventListener('scroll', e => {
    if (!shouldAllowScrolling) {
        window.scrollTo(lastSavedScrollLeft, lastSavedScrollTop);
    }
});

document.addEventListener('selectionchange', e => {
    shouldAllowScrolling = getSelectedText().length === 0;
});

If someone can offer a more elegant solution that prevents the scrolling entirely ill be happy to accept it.

EDIT:

this solution may cause light shaking/jittering.

that can be solved by performing the scroll natively through the WKWebView as opposed to calling window.scrollTo() in the javascript.
