Multi-touch interaction border reflow

[Sandstedt]

Bug:
In this example: https://mdn.github.io/dom-examples/touchevents/Multi-touch_interaction.html, the border during swipe-action is causing the other items to move (repaint / reflow) on the page, that in it's turn will trigger a non -swipe-button to be triggered as a swipe due to it's moved.

Solution:
Use some non repaint CSS like outline, or box-shadow instead of the dashed-border.

I agree that this could be better. I've updated the border usage to outline. Do you think this fixes the bug?

Yes it did :) Great!
