This extends across the system - Safari is great for battery life and hit or miss for performance, but it has an infuriating bug where it zooms out every webpage in Split View. There have been so many Stack Exchange and forum posts since 2013 on this issue and no action. Other WebKit browsers like Orion don’t do the same thing; it’s not a browser engine issue, so the only recourse is through Apple’s stupid feedback process that spits out autogenerated answers to everything. Windows is no better, but if Adobe, Affinity and a few medical anatomy apps opened the doors to something similar to Proton… jeez.
