Q: mouseleave not triggered when expected in A-frame

I'm trying to change the colour of some dynamically created box entities when the user mouses over/out from them.

They always successfully change on mouseenter, however it seems like mouseleave isn't always triggered so sometimes they keep the hover colour.

This is a basic version of my app:

<html>
  <head>
    <script src="https://aframe.io/releases/0.8.0/aframe.min.js"></script>
    <script>
      const COLOURS = {
        default: '#ff0000',
        hover: '#ffff00'
      };

      const blockMouseEnter = event => {
        event.target.setAttribute('material', 'color', COLOURS.hover);
      };

      const blockMouseLeave = event => {
        event.target.setAttribute('material', 'color', COLOURS.default);
      };

      AFRAME.registerComponent('stacks', {
        init: function() {
          const sceneElement = document.querySelector('a-scene');

          for (var stackHeight = 0; stackHeight < 20; stackHeight++) {
            const block = document.createElement('a-entity');

            block.setAttribute('geometry', {
              primitive: 'box',
              width: 0.5,
              height: 0.5,
              depth: 0.025
            });

            block.setAttribute(
              'position',
              `0 ${stackHeight * 0.5} -5`
            );

            block.setAttribute('material', 'color', COLOURS.default);

            sceneElement.appendChild(block);

            block.addEventListener('mouseenter', blockMouseEnter);
            block.addEventListener('mouseleave', blockMouseLeave);
          }
        }
      });
    </script>
  </head>
  <body>
    <a-scene stacks>
      <a-entity position="1 1.6 1" rotation="0 45 0">
        <a-camera>
          <a-cursor></a-cursor>
        </a-camera>
      </a-entity>
      <a-sky color="#5CC8FA"></a-sky>
    </a-scene>
  </body>
</html>

This is video of the problem, where there should never be more than one yellow brick.

Does anyone know why this might be?

It should be fixed in master versions of A-Frame soon going out as 0.8.2. Try https://github.com/aframevr/aframe/commit/000e669f8eb242ed7b1fe2ef45c5607d99d46609
