(User-visible)
On YouTube, you can generate the HTML code needed for embedding by using the video's "Share" feature. The resulting HTML includes the "allow" attribute, which will trigger an "Insecure HTML" error at the latest when the page is saved.
In addition, the dialog box contains a checkbox without a label.
Improvement
The "allow" attribute is now permitted for iframes. Additionally, the missing labels for the checkbox have been added.
Test
Launch the YouTube plugin and first verify that all checkboxes have labels. Then embed a video using the text field at the top. Afterward, save the TL Doc page. No error message should appear.
