Hello, it looks like there's an error in the code, I can't see any title when I click on the emoji card, here's the error on the console :
Uncaught TypeError: Cannot convert object to primitive value at RegExp.test (<anonymous>) at HTMLDivElement.<anonymous> (bootstrap.js:1434) at Function.each (jquery.js:381) at x.fn.init.each (jquery.js:203) at x.fn.init.t._jQueryInterface [as collapse] (bootstrap.js:1428) at HTMLDivElement.<anonymous> (bootstrap.js:1488) at Function.each (jquery.js:381) at x.fn.init.each (jquery.js:203) at HTMLDivElement.<anonymous> (bootstrap.js:1483) at HTMLDocument.dispatch (jquery.js:5429)
