Description
A plugin can use the blocks.getSaveElement to modify the saved output of a Gutenberg core block. I started documenting this here: #8470 (review)
For instance, I may want to write a plugin which adds a data-pin-description attribute to an Image Block:
<!-- wp:image {"id":33863} -->
<figure class="wp-block-image"><img data-pin-description="My Pinterest description" src="http://tastyrecipes.test/wp-content/uploads/2018/03/food-dinner-pasta-broccoli.jpg" alt="" class="wp-image-33863" /></figure>
<!-- /wp:image -->
However, if the plugin is deactivated after the user adds a Pinterest Description to their Image Block, the Image Block, the block will enter into an invalid, crashed state.
The Classic Editor permits manipulation of any HTML5 element, in accordance to the entire spec. It would be ideal of Gutenberg permitted the same: #6878 (comment)
