Template and stylesheet filters stopped working correctly.

[kemalcizoglu]

Stylesheet and template filters stopped working properly with WordPress version 6.4. When I examined it, a condition was added to run if the global variables $wp_stylesheet_path, $wp_template_path are null. However, these conditions did not exist before and if these two variables are not made null, the filters do not work correctly.

I think this problem will occur mostly on sites that use mobile themes. Because we use these two filters to present a mobile theme according to the user agent.

I just wanted you to be informed. Thanks.
