YouTube video embeds appear as plain URLs in Aztec

If I embed a YouTube video using the Calypso Classic editor, the embed expands and shows the video itself:

^{Firefox 69.0 on macOS 10.14.6.}

However, the Aztec editor in the Android app the YouTube video embed appears as a URL:

^{Tested with WPAndroid alpha-190 (13.3 alpha) on Pixel 3 Android 10.}

@mzorz would you consider this a duplicate of https://github.com/wordpress-mobile/AztecEditor-Android/issues/757 ?

@maxme since we are now moving to using the newer block editor, would you consider this issue a wontfix?
