Related: #11015

This pull request seeks to remove the Gutenberg-specific meta box compatibility functions, instead deferring to those shipped with WordPress 5.0.

Implementation notes:

The most tricky bit here is that we need the Gutenberg editor screen to claim itself as being the block editor, i.e. get_current_screen()->is_block_editor(). This should be the case anyways, but since core uses this function as a condition to perform some additional logic, it requires that those equivalent bits be disabled from Gutenberg as well.

From what I can gather, outside meta boxes, this impacts:

  • gutenberg_common_scripts_and_styles (reference)
  • gutenberg_enqueue_registered_block_scripts_and_styles (reference)

Testing instructions:

Verify that there are no regressions in the display and saving of meta boxes.

Is this to match the URL used in Core?

Do you think we could remove bootstraping Gutenberg entirely in the plugin (and just upgrade the scripts)

Yes, in fact, what I've done here is simply to align the bootstrapping to exactly what core does, in order to facilitate it being dropped altogether.

It mimics similar to what's done here:

https://github.com/WordPress/wordpress-develop/blob/8b4330bb6ea196005b5f0f84070b64c139f39b37/src/wp-admin/edit-form-blocks.php#L26-L28

It's important because there are conditions in core's handling of meta boxes which key off this value:

Without this, the the value of is_block_editor is false on the Gutenberg screen, which is clearly problematic irrespective of the specific meta box integration. For example, it forces plugin authors to do funny things to check whether the current screen is the block editor, regardless of whether that's the one in core or the one in the Gutenberg plugin.

Seems to work as intended but given the fragility of meta boxes, I'd like a second review. Maybe @noisysocks
