5.9.0-RC1 - Setting 'align_content' => 'matrix' throws React error in WP < 5.5

After upgrading to ACF Pro 5.9.0-RC1 I ran into JS errors on blocks having set ['align_content' => 'matrix'], probably sure because the site is running on WordPress 5.4.2 and lacks from the new matrix control.

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `r`.

Reproduce the block editor error with ACF Pro 5.9.0-RC1 on WordPress 5.4.2 using a block whose align_content is set to matrix. Start by tracing the matrix control integration indicated by the React stack trace and compare it with WordPress 5.5 behavior; done means the block editor no longer throws the invalid React element error on older supported WordPress versions.
