Add AMP under "Preview" dropdown in WordPress

[simison]

Hi! I wanted to let you know that it's now possible to add items under "Preview" menu in Gutenberg since:

• Editor: Add extensibility to PreviewOptions v2 WordPress/gutenberg#64644

More here: https://make.wordpress.org/core/2024/10/18/extending-the-preview-dropdown-menu-in-wordpress-6-7/

I recommend moving the AMP preview there from the plugin toolbar conditionally when PreviewDropdownMenuItem is available:

The original issue at Gutenberg repo used AMP as an example of why the Preview dropdown had to be extendable:

• Allow external preview links in Preview dropdown to be extended WordPress/gutenberg#25309

I wrote more ideas here on how to improve preview extensibility. Feel free to share AMP perspective!

• Allow extending editor preview in more ways WordPress/gutenberg#65005

Perhaps for another issue, but I noticed the 'Preview in new tab' line has more left/right padding than the rest of the items.

This is great as I understand it will eliminate some brittle code we've had to implement to work around this limitation:
