TinyMCE sandboxes scripts in iframes

Post by perissf » Wed Apr 24, 2024 5:10 pm

Hi,
I noticed that there is no way to allow iframes with JS (like [youtube] embed) with TinyMCE editor because it inserts a sandbox attribute.
Apparently there is a recent TinyMCE option to allow it (TINY-10348), but it's not available in the plugin options.

I confirm it. I put to article:
<iframe src="https://drive.google.com/file/d/gkhbjfblkjgdf/preview" width="2000" height="700" allow="autoplay"></iframe>
and TinyMCE adds sandbox="" attribute automatically:
<iframe src="https://drive.google.com/file/d/gkhbjfblkjgdf/preview" width="2000" height="700" allow="autoplay" sandbox=""></iframe>
and result is embed file shows only first page. I need to change editor to none under my profile (i tried only this) and then i go to edit article again...
