Does anyone have any information on the following warning that I am seeing in the CE 2.4.2 CMS and Block content areas on save?
Temporarily allowed to save HTML value that contains restricted elements. Allowed HTML tags are: div, a, p, span, em, strong, ul, li, ol, h5, h4, h3, h2, h1, table, tbody, tr, td, th, tfoot, img, hr, figure, button, i, u, br, b
It appears to be produced by saving content with html that contains things like data toggles, iFrame embeds, etc. I've got WYSIWYG turned-off globally, but the warning still gets produced.
I believe it has showed-up after my Magento 2.4.1 - 2.4.2 upgrade, but can't seem to find any information online in regards to the warning, so I'm wondering if anyone has any info here.
Are data-toggles, iframes and such going to be eliminated in a future release of Magento?
How soon do we have? Next version? Magento 2.5?
Will we be able to whitelist some/all of these items for use in admin content areas?
