Extension forces focus on new tab opened in the background

When the fake pinned tab is viewed, it creates a new tab if one doesn't already exist, and then forces a switch to this adjacent tab. Now, if 'Open link in new tab' or the middle mouse button is used on a link to create and load a new tab in the background, this extension again forces a switch to this new tab once it starts loading. This is unexpected, since Chrome opens new tabs in the background, without jumping to them.

Further opening of new tabs works as expected, until the pinned tab is viewed again (manuakky or after closing all tabs).
