Mousedown on Chrome 55 [closed]

I use the mousedown event in JS to assign an action to my object in a project in question.

With the new Google Chrome update for version 55 my event no longer works!

Does anyone have any idea how to use the event in this new release?

I currently use the following form.

var iddiv = document.getElementById('meuid');

iddiv.addEventListener('mousedown', function(e) {
});

Thank you all!

iddiv.addEventListener('click', function(e) {
    divSelc = e.target.id;
$("#"+divSelc).css("outline","3px solid red");
});
