I am very happy that they are continuing to fix and improve the game after release! The last patch had two things I really wanted: 1) The game prioritizing your avatar as the main speaker when dialogue triggers automatically, and 2) Fixing Halsin’s missing barks.
So with the game prioritizing your avatar as the main speaker thing, I don’t think it’s actually fixed. I’ve seen two cases where a companion was selected over the avatar for a very important cutscene. Act 3 spoilers
First, in the scene in the Astral prism at the transition point between acts 2 and 3, Astarion took center stage in the cutscene where you first entered the prism. Then in the lower city during a long rest, Astarion’s siblings came to abduct him. After that fight, Shadowheart was selected to speak to Astarion rather than the avatar.
So as with the persistent “Continue” bug, I’m not confident that this issue has actually been addressed. (No mods for the scenes I mentioned and both occurred after patch 6.)
