Actual results: Private browsing content is exposed after closing the private browsing session. Expected results: No private browsing content exposed after closing said session.
I'm not following the movie -- can you describe each scene/step? The only thing you opened in private browsing that I saw was github, and I don't see that leaked into your non-private session.

The video opens with the mozilla.org website open in a private browsing. I then exit private browsing, and the private mozilla.org tab shows on switching tabs in the non-private session. I then open github, and close private browsing. Switching tabs again in the non-private session still leaks the mozilla.org website.

Not a remote attack so doesn't need to be hidden.
