Right-aligned captions with embedded iframes get removed in Visual mode

[ChrisBAshton]

This has affected a client site a couple of times now so I thought I'd better share it and see if this is a bug or if there is something we are doing fundamentally wrong.

If you are working in Text mode and you end up creating a caption, right-aligning it and embedding an iframe within the caption shortcode, as follows...

[caption width="350" class="alignright" caption="Ria Ritchie's latest video on YouTube"]<iframe width="350" height="197" class="alignright" src="https://www.youtube.com/embed/_W9f5onA6nc?rel=0&amp;showinfo=0" frameborder="0" allowfullscreen></iframe>[/caption]

...if anyone comes along in Visual mode they can see the embedded iframe right-aligned and with the caption below it. If they make a change to any part of the post and hit 'Update', the caption and iframe get removed, but the caption text remains (without any surrounding markup).

Hi @ChrisBAshton,

Welcome to Trac! And thanks for this ticket. My apologies that it took so long to receive a response.

The [caption] shortcode is actually only meant to be used with <a> and <img /> tags. I think this is working as expected.

I am going to close this out, but if you feel <iframe>s should be allowed within captions, feel free to reopen with some more details.
