Shortcode Embeds: Instagram oEmbeds not displaying properly in wp-admin editor

[emrikol]

Steps to reproduce the issue

Enable "Shortcode Embeds" and add an Instagram oEmbed (ex: https://www.instagram.com/p/BYMDTB5g95n/)

What I expected

I expect to see the rendered embed in the editor:

What happened instead

Instead, I see a broken Instagram embed:

This can also be fixed by removing the Jetpack embed provider and re-adding the core provider, in a pinch:

add_action( 'init', 'add_core_oembed_provider' );
function add_core_oembed_provider() {
    wp_embed_unregister_handler( 'jetpack_instagram' );
    wp_oembed_add_provider( '#https?://(www\.)?instagr(\.am|am\.com)/p/.*#i', 'https://api.instagram.com/oembed', true );
}

This issue has been marked as stale. This happened because:

• It has been inactive in the past 6 months.
• It hasn’t been labeled `[Pri] Blocker`, `[Pri] High`.

No further action is needed. But it's worth checking if this ticket has clear reproduction steps and it is still reproducible. Feel free to close this issue if you think it's not valid anymore — if you do, please add a brief explanation.

We are also seeing this with WordPress 5.3 with the Block Editor enabled. As with WP-Admin disabling jetpack_instagram and re-enabling core's provider does workaround the problem.

Good point. I'll close this issue in favor of #9331, where we track the issue within the Block editor.
