Comment 4 for bug 1652997

Hi, I tried reproducing the bug today, but it seems that there is a different issue with the embedded code provided by the user on the forum.

<div style="position:relative;padding-bottom:56%;padding-top:20px;height:0;"><iframe src="https://media.xjtlu.edu.cn/player?autostart=n&fullscreen=y&width=0&height=0&videoId=5656&quality=lo&captions=n&chapterId=0" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;" allowfullscreen></iframe></div>

After using the code above as an external media source, the generated block on my profile only had an empty iframe:

<div style="padding-bottom:56%;padding-top:20px;height:0;">
    <iframe scrolling="no" style="width:100%;height:100%;" allowfullscreen="" frameborder="0">
    </iframe>
</div>

I tried doing the same thing on the live mahara website, and even removing the <div> tags, but the problem persisted.

May I ask in which files the iframes are validated/edited by mahara before being displayed on the website?

Cheers
