浏览器扩展无法绕过targetB网站CSP限制重定向指定JavaScript URL的问题求助

大家好，我最近在开发一款基于Manifest V3的Chrome浏览器扩展时遇到了一个棘手的问题，想请各位帮忙排查一下：

我需要重定向两个目标网站的特定JavaScript URL，其中targetA的重定向功能正常生效，但targetB始终无法工作。排查后发现，targetB的HTML文件中设置了CSP（内容安全策略），这个策略限制了我要重定向的JavaScript URL请求。我尝试过用modifyHeader规则来移除X-Frame-Options和Content-Security-Policy响应头，但完全没有效果。推测targetA没有启用CSP限制，所以重定向能正常运行。

下面是我的扩展配置文件，麻烦各位帮忙看看哪里可能出了问题：

manifest.json 文件 #

                "url": "http://127.0.0.1:3600/targetA/target.js"
            }
        },
        "condition": {
            "urlFilter": "https://www.targetA.com/target.js",
            "resourceTypes": [
                "script"
            ]
        }
    },
    {
        "id": 3,
        "priority": 1,
        "action": {
            "type": "redirect",
            "redirect": {
                "url": "http://127.0.0.1:3600/targetB/target.js"
            }
        },
        "condition": {
            "urlFilter": "https://targetB.org/target.js",
            "resourceTypes": [
                "script"
            ]
        }
    }
]

另外，我还尝试过调整规则的priority参数值，测试了不同的优先级组合，但问题依然存在，targetB的JavaScript URL始终无法被成功重定向。
