Issue #4456 – Created in Classic then converted

This post was created using the Classic editor then Edited using Gutenberg.

OneTwoThree ABC DEF

The carefully crafted new lines have been removed. The new editor does not respect new lines in shortcode content. It’s impossible to use the new editor to edit posts which depend on this.

For me this is a blocker; it breaks my sites.
