The content scripts specified in the manifest of an extension should be loaded each time a user visits a web page. However, in the iOS 15 simulator, the content script is only loaded the first time that the extension is enabled -- either when you grant permission for the site, or if you turn the extension off and back on while on a site. Otherwise, the content script is not injected. This is clearly a bug, right? Is there a known workaround or a fix in the works?
