Remove the classic theme style after upgrading WordPress 6.1

After upgrading to WordPress 6.1, check the source code and find a style code in the header:

 <style id='classic-theme-styles-inline-css' type='text/css'> /*!  This file is auto-generated */ .wp-block-button__link{color:#fff;background-color:#32373c;border-radius:9999px;box-shadow:none;text-decoration:none;padding:calc(.667em + 2px) calc(1.333em + 2px);font-size:1.125em}.wp-block-file__button{background:#32373c;color:#fff;text-decoration:none} </style>

It is probably prepared for WordPress default theme that does not have site editing function, but the default theme that is not used also has this, which is inexplicable, and should be automatically added by the system.

Removal method, Add the following code to the current theme function template functions.php:

 add_action( 'wp_enqueue_scripts', 'zm_remove_classic_heme_styles', 20 ); function zm_remove_classic_theme_styles() { wp_dequeue_style( 'classic-theme-styles' ); }

Or simplified code:

 add_action( 'wp_enqueue_scripts', function() { wp_dequeue_style( 'classic-theme-styles' ); }, 20 );

feel WordPress Developers are making mistakes again.
