Touch scrolling inside dropdown broken on mobile

[BrechtVds]

Describe the bug
When touch scrolling inside a dropdown the window gets scrolled instead of the dropdown options.

To Reproduce
Steps to reproduce the behavior:

1. Go to the Choices demo site on mobile
2. Click on the "Fake Tales Of San Francisco" dropdown under "Single select input"
3. Try scrolling the options inside the dropdown
4. The options will scroll a tiny bit, but then window scrolling seems to take over

Expected behavior
The dropdown should scroll, not the window.

I can't reproduce this issue with Android 9 and Chrome 83.

I have also run into this issue with iOS Safari

I have also this problem with iOS. Interesting thing is, that when you select a value from the list once, it starts to work as it should. So it doesn't work only on the initial load of the page

This is how I fixed it:

choices.passedElement.element.addEventListener('showDropdown', () => {
    $('.choices__list').hide();

    setTimeout(() => {
        $('.choices__list').show();
    }, 1);
}, false);

This is how I fixed it:

choices.passedElement.element.addEventListener('showDropdown', () => {
    $('.choices__list').hide();

    setTimeout(() => {
        $('.choices__list').show();
    }, 1);
}, false);

@southofthree For me this just keeps the menu hidden and breaks completely. Did you add something else?

@aaronjpitts no, nothing else

I am not able to replicate this anymore as of iOS 14, so it looks like Apple might have fixed something on their end.

Then this could be closed, no?
