From https://github.com/clach04/clay/blob/4641292d3d92b5a4f91a4a8544eebe7577b3d051/index.js#L154

var emulator = !Pebble || Pebble.platform === 'pypkjs';
....
if (emulator) {
....

Done in commit 39c1e18 - however, turns out there was another way. Custom actions appear to get around browser behavior and Clay then works in emulator. Code left in so that emulator can be detected should that be needed.
