I found that on most of iPhone devices, the address bar is at the top when the phone is landscape. But for iPhone SE, the address bar is at the bottom. I want to know if there logic for the position of the address bar during landscape ?

device: iPhone 7here is the screenshot of instrumenting that iphonehttps://upload.cc/i1/2020/06/08/6pehiM.pngit is quite easy to reproduce, just to find a html5 heavy page, e.g. youtube or some html5 games, and then keep on refreshing.the memory usage will go up to 1g, and then webkit crashes due to out-of-memory.while I cannot reproduce this on older ios version from 13.3. the memory will not grow that fast.I want to know if there is any memory "optimization" or restriction after ios 13.4?btw, I have tried the latest ios 13.5.1, same crash happens.
