Always Filter Admin Bar Showing
|Reported by:||filosofo||Owned by:||filosofo|
We can't anticipate every use of the admin bar, and there's no great performance benefit in short-circuiting the show_admin_bar filter as done in r16221.
For example, suppose someone wants to load the admin bar markup asynchronously. It would be helpful to be able to turn it on when DOING_AJAX is true.
