Providing more details:
We are using the custom HTML markup to generate the AddThis tool box, below is our code for the markup.
<div class="addthis_toolbox addthis_default_style">
<a class="addthis_button_twitter"></a>
<a class="addthis_button_facebook"></a>
<a class="addthis_button_linkedin"></a>
<a class="addthis_button_compact"></a>
</div>
When WordPress + AddThis plugin renders this, it comes out being LinkedIn the only link that includes target=”_blank” attribute, all of the rest share buttons doesn’t have this.

Hi Elvis,
Thanks for the information and feedback. We don’t currently have a way to change the behavior, as it’s hard-coded. I’ll pass the suggestion along to our product team for consideration in a future version.
Thanks!
@addthis_matt Sounds good, yeah looks to me that this one on LinkedIn might have left behind and needs some revision now. Currently is a bit inconsistent UX experience when you compare how other popular share buttons open like, Facebook, Twitter, etc, they all open in a separate pop-up window.
Thanks for taking care of this with your team!
