Weird functionality of current_theme_supports('title-tag') in WordPress 4.4

[gnotaras]

It seems that current_theme_supports('title-tag') returns false for themes that have the title-tag feature enabled, like TwentyFifteen, under WordPress 4.4.

Where are you checking current_theme_supports('title-tag')? Theme support is added during the after_setup_theme action, so if you check it further up it won't work.

Tests_General_DocumentTitle and Tests_Theme_Supportcheck for that, so I'm not sure something broke in 4.4

Oh, I see. I used the following code in a testing plugin (was trying to add some logic based on the theme's features), while the TwentyFifteen theme, which has title-tag support, was activated:

if ( ! current_theme_supports('title-tag') ) {
    var_dump('12345');
}

Now I see this was a mistake. Please feel free to close this issue as invalid.

Thanks for your response and I'm sorry about that!
