Embed block: Inline preview cut-off when editing URL

[fluiddot]

Describe the bug
After creating an Embed block and only depending on the provider used, editing the URL with one from a different provider can lead to a cut-off of the inline preview.

To Reproduce

1. Add an Embed block.
2. Set a YouTube URL (example: https://www.youtube.com/watch?v=ssfHW5lwFZg).
3. Tap on the pencil icon button, located in the toolbar, to edit the URL.
4. Set an Instagram URL (example: https://www.instagram.com/p/Bl6LgZgFDOm).
5. Observe that the inline preview is cut-off.

Expected behavior
Inline previews should display the entire content.

I compared the HTML produced by this case and creating an Instagram embed from scratch and looks like, in the first case, it's adding extra attributes that might be leading to the cut-off, specifically the following ones:

• "responsive":true
• "className":"wp-embed-aspect-16-9 wp-has-aspect-ratio"

HTML of setting Instagram URL to YouTube embed:

<!-- wp:embed {"url":"https://www.instagram.com/p/Bl6LgZgFDOm","type":"rich","providerNameSlug":"instagram","responsive":true,"className":"wp-embed-aspect-16-9 wp-has-aspect-ratio"} -->
<figure class="wp-block-embed is-type-rich is-provider-instagram wp-block-embed-instagram wp-embed-aspect-16-9 wp-has-aspect-ratio">
    <div class="wp-block-embed__wrapper">
https://www.instagram.com/p/Bl6LgZgFDOm
    </div>
</figure>
<!-- /wp:embed -->

HTML of Instagram embed:

<!-- wp:embed {"url":"https://www.instagram.com/p/Bl6LgZgFDOm","type":"rich","providerNameSlug":"instagram"} -->
<figure class="wp-block-embed is-type-rich is-provider-instagram wp-block-embed-instagram">
    <div class="wp-block-embed__wrapper">
https://www.instagram.com/p/Bl6LgZgFDOm
    </div>
</figure>
