I have encountered the same problem, do you have a solution? My solution is to refresh the webview after a pop-up window, but I'm not sure if it's safe.

same here，on iOS 18.3.1 If the click event in flutter is clicked, the webview no longer responds to the click event of the web page.

This is a bug in the Flutter engine, which seems to have been fixed in Flutter 3.27.4 version
