The WKWebView browser backs up the previous page, causing the page on the previous page to have no layout rendering and a white screen. Returning the WKWebView page to the previous page will not re-execute the script script, nor will it trigger the reload event. This may be due to the page management and caching mechanism of WKWebView, which causes the previous page to appear white screen and the layout is not successful.
