Open Event links in new tab

I want to have some event links open in a new tab. I do this by adding target=”_blank” to the anchor tag in #_EVENTLINK and in #_EVENTIMAGE (using the em_event_output_placeholder filter). This works correctly in List view but in Grid view it opens the url in a new tab but also redirects the current tab to the target url. This problem is due to the following code in events-manager.js:

    $(document).on('click', '.em-grid .em-item[data-href]', function(e){
        if( e.target.type !== 'a' ){
            window.location.href = this.getAttribute('data-href');
        }
    });

Commenting out the above code fixes the problem. What is the purpose of this code and why is it necessary? This was introduced in version 6.3 in changeset 2849382

I hope this can get fixed in the next release.
