There is a problem with Alt-clicking on layer icon. Sometimes it does not activate isolated editing, instead viewport is blinking and nothing changed (instead of switching into layer content). So it is a 50/50 experience. Problem most prominent when alt-click on icon, but sometimes happen with alt-clicking on name
Look at video, the switching layers here is with Alt holding down (so every selected layer change should enter isolated editing for layer)
