NSFW not closed popup

[mapx-]

uBo 1.14.19.101
chrome 63

go to http://imgadult.com/img-5a1a3afb33591.html

I added these filters:

/url2.php*$popup
||imgadult.com^$script
@@||imgadult.com/newimg.js.php$script
@@||imgadult.com/js/jquery$script

click "continue...." at the top
sometimes you have to click twice to get the image in the original tab
A new tab is opened something as http://imgadult.com/url2.php?i=7 which is not closed by the first filter !

In the original tab finally I get the wanted image.
Click on page => ...surprize => a popup is quickly closed by ...the first filter.

Why this behaviour ?

It's a bug in uBO, this needs fixing. The bug is that uBO wrongly detects http://imgadult.com/url2.php?i=7 as not different than javascript:;, because it tries to find a :// in the URLs.
