<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Editor: Fix deprecation notice in block editor.
In <a href="https://core.trac.wordpress.org/changeset/56682">[56682]</a>, the `print_emoji_styles` function was deprecated and a corresponding deprecation notice was added. In order to maintain backward compatibility, `print_emoji_styles` was retained as a hook into wp_print_styles. This resulted in the appearance of deprecation notices within the block editor. The root of this issue was the manual invocation of the `wp_print_styles` function in block-editor.php. To address this, the `print_emoji_styles` callback was manually removed, `wp_print_styles` was called, and the action was subsequently rehooked, resolving the deprecation notice within the block editor.
