brent Like I said, mediocre but not a dealbreaker and no browser is perfect
As you might already know, I use Vivaldi on all my devices -- including the Windows machine that streams to my TV -- and I was really surprised to learn that setting its magnification was on a per-site basis. I set it to 130% for this forum, and if it ever changes by itself, I've never noticed. It helps me to avoid typos, as it makes it easier to read the text which is otherwise very small on this HD laptop screen.
If it ever resets itself, I'm pretty sure it doesn't do that within a session, and using hibernation, my sessions last a very long time. It's so easy to reset it with that little slider, I've never thought of it as a problem.
I've wondered for a long time why you seemed so determined not to try Vivaldi. I'm happy you've finally given it a chance.
