If filterlist is blacklisting src URL of Iframe , the whole page fails rendering

[Vineeth-Mohan]

We have been observing this when we blacklist certain ads like googletagmanager.com , this might come as src in iframe . Instead of avoiding the iframe , the entire page render fails giving error like below.

I feel this is a serious issue and I cannot find a work around for this. Either we need provision to disable iframe or this error should not affect the rendering of the page.

Did you ever find a workaround?
