  1. Just like the title.
    Scenario: When the iOS webview frequently switches pages, responseStart > responseEnd will occur

I really haven’t noticed this situation. I just read the specification and it doesn’t look like a normal situation. I suspect it is an implementation bug of webview.
Please elaborate on the reproduction steps: If it can be reproduced frequently, submit a bug to iOS~
