Widgets: Fix warning when widgets block editor is disabled #30318

Description

Fixes #30305.

If a core widget is unregistered then it will not be in $wp_widgets_factory→widgets which causes a PHP warning.

We also don't need to set show_instance_in_rest on WP_Widget_Block since it already declares this.

How has this been tested?

  1. Comment out add_theme_support( 'widgets-block-editor' ); in lib/init.php.
  2. Load WP Admin.
  3. There is not a PHP warning.

Types of changes

Bug fix.

If a core widget is unregistered then it will not be in
$wp_widgets_factory->widgets which causes a PHP warning.

I tested this by adding remove_theme_support( 'widgets-block-editor' ); and then after a refresh trying to access the widgets page and to edit a post. It worked as expected.
