Try to give anonymous function into .filter()

I think, my solution will help you:

//
// jQuery 3 pseudo ':hover' doesn't support
//

// Working on jQuery 1.7.1
$("*").on('click', $.proxy(function() {
    if ( this.$('.tooltip:hover').length > 0 ) { // jQuery 3.2.1 -> Uncaught Error: Syntax error, unrecognized expression: unsupported pseudo: hover
      console.log('Hovered!');
    } else { 
      console.log('Where is my element!?'); 
    }
}, this));


// Updated solution for jQuery 1.7.1 - 3.2.1
$("*").on('click', $.proxy(function() {
    var isHovered = $('.tooltip').filter(function() {
        return $(this).is(":hover");
    });

    if ( isHovered.length > 0 ) {
      console.log('Hovered!');
    } else { 
      console.log('Where is my element!?'); 
    }
}, this));
