After clearing browser cache, your demo page started working again for me.
However I still can't get it to work locally. I've tried Chrome, Firefox, and Edge, clearing cache on all browsers. I can try modifying browser settings
Okay @enchev I tracked this down to a specific commit: 4.25.12
When I run your solution locally, version 4.25.11 and prior work as expected.
When I switch to version 4.25.12 and newer, it no longer functions correctly.
Tried Chrome, Edge, and Firefox.
Clearing cache does not help either.
