On iPhone it opens the keyboard initially when clicking in your demo... Seems like a bug
Was using an input tag for the demo. changed it to button. Thanks for informing.
Demo link (in README.md) still fails on an iPad. I think it has tondo with the link being inside an H2 heading. When I attempt to click, I see a link icon appear to the left of the "Demo" text, but no amount of clicking will cause the link to open.
