I’ve noted that sometimes it happens and sometimes it doesn’t. However, the warning that Chrome throws is the same as if the website tried to open a popup without user interaction (with the options “Always allow popups from X” or “Continue disallowing popups”).
I’ve seen this problem on multiple templates which makes me think that it’s more plugin-related than template-related.
I’ve had this happen to me with Chrome, and it’s not like it’s completely blocking the link click, but users have to allow popups from the site to do that, and most of them won’t be eager to do so because of the danger it could imply.
Hope this helps.
