What I long press then ‘open in a new tab’ what see is something trying to do a pop up and then it interacts with the slide-out side panel, and the side panel doesn’t collapse all the way so it’s just long vertical side panel bar, that’s showing the right side of a search box with the magnifying glass, and it covers about 1/5 of the screen so it makes it really hard to read the article.
