Is Blorp supposed to clone the default browser process like this?

When I click an external link from inside the app, Blorp replicates appears to open a new instance of my default browser, including all of its current tabs. It's slightly confusing because closing the tab I opened from some thread means I now have two identical browsers open, but one of them is Blorp 😉

I realise I'm just supposed to hit the back button to be returned to the app UI, but I'm new to Blorp and very familiar with my browser. You see how habits win out over what I rationally know I should do...

Did I miss some setting to open links in an internal, single tab browser instead?
