--- Comment #2 from Wenson Hsieh <wenson_hsieh at apple.com> ---
I think we can fix this by relaxing this check:

```
(in WKContentViewInteraction.mm:)

    if (gesture == UIWKGestureLoupe && _positionInformation.selectability == WebKit::InteractionInformationAtPosition::Selectability::UnselectableDueToUserSelectNone)
        return NO;

```

...to something like this instead:

```
(in WKContentViewInteraction.mm:)

    if (gesture != UIWKGestureOneFingerTap && _positionInformation.selectability == WebKit::InteractionInformationAtPosition::Selectability::UnselectableDueToUserSelectNone)
        return NO;

```

I _suspect_ the choice to limit this to only the Loupe gesture was made to (1) limit risk, and (2) to make it so that the user can always still tap in `-webkit-user-select: none;` regions to clear an existing selection.

One workaround here would be to add active touch event listeners and prevent `touchstart` and/or `touchend`.
