Any intuition on why we’d expect opening the same page on a newly implemented browser engine that implements all equivalent standards and functions will consume less resources?
That’s not an expectation. The experience is that this became a reality thanks to google, and that it will only get worse in the future. More competition within browsers is the expectation. Better chance for better frameworks to emerge. Eventually it may cause google code to shift into a better overall state too.
