Loom embed support

[Kartik Suthar]

When pasting the loom video URL it will convert to an Embed block automatically

But it will not be rendered properly on the front-end and creates a white space:

This is because of the below attribute added to the embed iframes added by WP.

sandbox="allow-scripts"

If we add custom html block without this attribute, the loom embed works.

e.g.

<iframe class="wp-embedded-content" security="restricted" title="Loom Use Case: Saying Congratulations " src="https://www.loom.com/embed/cd7cf15849574e608a696a1c6646f043#?secret=xfpTfjVrI0" data-secret="xfpTfjVrI0" frameborder="0" width="640" height="480"></iframe>

Hello @kartik-suthar Welcome to trac and thanks for creating this ticket.

WordPress has added a "sandbox" attribute to iframes for enhanced security. Loom attempts to read the cookie, which is not permitted when the sandbox mode is enabled.

To resolve this issue, you should reach out to Loom.
