[2.6.0] Exp Columns - Shortcode columns no longer wrapped with div .layout-column-1 class

[opicron]

On 2.5.0 shortcode columns in experimental columns block are wrapped in a div with the class layout-column-1. In 2.6.0 this no longer seems to be the case.

See #5935 and #5351.

When you say "wrapped", do you mean in the markup saved for the post, or as shown in the editor?

Nevermind, I was able to reproduce. I think this was a subtle change introduced in #5897 where we're no longer applying a div wrapper to RawHTML contents. It was originally this way because blocks apply a default set of props, including classname, and otherwise there is nothing to which to apply the props. RawHTML should include the wrapper for these cases, and otherwise the children verbatim.
