Interactions stay disabled after touching an ignored element

[gaellafond]

Issue:
Interactions are not working after scroll page + touch the map, on mobile.

How to reproduce:

1. Scroll the page by touching the map with one finger. The "Use 2 fingers to move the map" appear.
2. Touch the map before the message disappear.
3. The interactions are disabled and are never re-enabled. This causes issues such as clickable map elements such as polygons are no longer clickable, the zoom out button zoom the map in when double click, etc.

NOTE: The bug is also reproducible with Google Chrome desktop, when mobile device is turned on in the developer tools.

Solution:
Add the following line:

this._enableInteractions();

in method _handleTouch

        _handleTouch: function (e) {
            //Disregard touch events on the minimap if present
            var ignoreList = ["leaflet-control-minimap", "leaflet-interactive", "leaflet-popup-content", "leaflet-popup-content-wrapper", "leaflet-popup-close-button", "leaflet-control-zoom-in", "leaflet-control-zoom-out"];

            var ignoreElement = false;
            for (var i = 0; i < ignoreList.length; i++) {
                if (L.DomUtil.hasClass(e.target, ignoreList[i])) {
                    ignoreElement = true;
                }
            }

            if (ignoreElement) {
                if (L.DomUtil.hasClass(e.target, "leaflet-interactive") && e.type === "touchmove" && e.touches.length === 1) {
                    L.DomUtil.addClass(this._map._container, "leaflet-gesture-handling-touch-warning");
                    this._disableInteractions();
                } else {

                    // ###### HERE ######
                    this._enableInteractions();

                    L.DomUtil.removeClass(this._map._container, "leaflet-gesture-handling-touch-warning");
                }
                return;
            }
            ...

I had a similar problem: on desktop when users mouse over a Polygon and then mouse back over the underlying tile layer, they can't click + hold to drag the map. This solution fixed that too.
