All-caps link titles in Links widget are wrapped in span

Thanks for the report. It looks like this is a bug in wp-Typography that has been more or less forever. I wanted to classify it as WordPress Core bug initially, but since that code is so ancient, there is no point in creating a ticket for this.

I’ll remove the filter in the next release of wp-Typography. Meanwhile, you can disable the filtering via \remove_filter( 'link_name', [ \WP_Typography::get_instance(), 'process' ], 9999 );

Thanks Pepe. Where would this code go? In my themes functions.php?

Yes, into functions.php.

Thanks, though that doesn’t seem to be working for me.

Ah ok, of course, I had to add it as an action:

add_action( 'wp_loaded', function() {
  remove_filter( 'link_name', array( WP_Typography::get_instance(), 'process' ), 9999 );
});

Will be fixed in 5.7.2.
