Current Behavior

在使用mrec和banner时，如果配置的广告是admob，会无限创建webview，导致app性能消耗极大，大量出现anr。
我们测试一下Max SDK版本以及admob SDK的版本，max版本为3.11.1（android版max sdk 12.6.1）及之前的版本没有问题（创建的webview个数维持着12个左右），但升级到高版本（4.0.0及之后的版本）就会大量创建webview用于广告展示。

When using MREC and banner ads with AdMob configured, an unlimited number of WebViews are created, significantly impacting app performance and leading to a large number of ANRs.

We tested the versions of the Max SDK and AdMob SDK. For the Max SDK version 3.11.1 (Android Max SDK 12.6.1) and earlier, there were no issues (the number of WebViews remained around 12). However, upgrading to higher versions (4.0.0 and later) resulted in a large number of WebViews being created for ad display.

Expected Behavior
