Shortcode(s) or URL(s) you used for embedding and have problems with: Not a shortcode issue
Detailed Description of the issue: Embedded youtube videos added as a Gutenberg block appear with a massive top margin when ARVE is active. ARVE shortcode embedded videos and videos inserted with the classic editor (even classic editor block within Gutenberg) are fine.

Fixed in 8.9.9 thanks for reporting. I am not up to speed on Gutenberg but I plan integration. Sadly there is no shortcode UI alternative for it yet but there are previews for those standard embeds without shortcodes.
