With a physical iPhone attached to the dev tools on my laptop, the memory usage of this web page https://nypost.com/2023/10/11/australian-swimmers-almost-walk-into-shark-as-it-swims-close-to-shore/ consistently grows until it reaches the memory limit of the device (in my case, about 1.5GB) The safari dev tools has a memory profiler timeline which breaks down memory usage into categories including "Javascript", "Layers", and "Page"; is there a way to break these down further to individual scripts/resources? I have also tried looking at the Javascript allocations profiler, but the computed heap size reported in its snapshots never comes anywhere close to the 700+ MB of "JavaScript" memory usage reported by the Memory profiler.
