Also a bug for me and has been for a couple years now.
It’s a huge pain point during handover when I send someone a whole bunch of links but they go to the parent frame rather than the selected frame. Whoever is clicking my links ends up lost, confused as heck. I then have to go back in and update every link again manually by right clicking. It also makes me lose trust in this feature altogether.
Dramatic? No! SPARE ME! I’M A SHORTCUTS MAN! MOUSES ARE FOR WHEN SHORTCUTS DON’T EXIST AND SOMETIMES THEY EAT CHEESE
