Let ID-less [gallery] shortcodes fall to Shortcode block #25144

Fixes #11551

Description

Until now, the Gallery block was the recipient of all [gallery] shortcodes. This works well for the most common use of the shortcode, when identifiers for media objects are specified ([gallery ids="1,2,3"]) but fails to accommodate other scenarios, as detailed in comments in #11551, especially whenever WordPress post attachments are concerned (e.g. [gallery], [gallery id="10"]).

This pull request adds an isMatch predicate to the Gallery block's shortcode transform so that it only catches shortcodes which explicitly provide gallery objects via the ids attribute. Otherwise, assume that the shortcode is doing more work than the Gallery block can automatically accommodate and let the transform be picked up by the Shortcode block — thus leaving the original shortcode untouched.

How has this been tested?

Using the Classic block (or Classic editor, or the CLI), create a draft with the following shortcodes:

  • [gallery ids="1,2,3"], where the integers represent the IDs of existing media library images
  • [gallery], assuming that there are images attached to the present post (but not needed for the purposes of testing)
  • [gallery id="1"], assuming that 1 is the ID of a WP post with attachments

Press the Classic block's Convert to Blocks button. Verify that the first shortcode is converted into a Gallery block with the expected images. Verify that the remaining shortcodes are converted into Shortcode blocks and that the shortcodes therein are preserved.

The same should happen by directly pasting these shortcodes onto the block editor.

Types of changes

Enhancement. Backwards compatibility.
