What problem does this address?

Focus settings for background images are not currently image-specific. When creating patterns that use focus settings in a background image the "cropping" of an image may appear confusing to users who have not yet encountered this block setting.

Describe the bug:

Using the provided serialized block content, the block fails validation when it previously did not.

To reproduce:

<!-- wp:coblocks/map {"address":"Scottsdale Arizona","pinned":true,"height":534,"align":"full"} -->
<div style="min-height:534px" data-map-attr="/qaddress/q:/scottsdale arizona/q||/qlat/q:/qundefined/q||/qlng/q:/qundefined/q||/qskin/q:/qstandard/q||

It would be cool to have an additional parameter when creating a BlockStory to allow to create stories for Mobile as well as Desktop.

I'm not sure wether we should just have a Boolean to toggle between mobile & Desktop, have an array of different possible screen sizes or just pass through the viewportWidth to the BlockPreview component.

We want to have our interface for gutenberg project in Portuguese.
File with strings to translate in json is here https://github.com/openzim/gutenberg/blob/master/gutenbergtozim/l10n.py and you should add you locale here : https://github.com/openzim/gutenberg/blob/master/gutenbergtozim/export.py#L40

I could see a need for an admin alert when Gutenberg is turned off for all post types just so a user is aware. It could be set to be dismissible forever. I think some feedback on activation of the plugin would be nice.

The text could be something like:
`Notice: The Gutenberg ramp plugin has disabled Gutenberg on the post, pages, ______, _______, etc. post types. If you would like to activate
