The ‘wp-admin/admin-header.php’ file outputs ‘viewport’ meta information. It appears the worth of the viewport is difficult coded into the file. (See: https://github.com/WordPress/WordPress/blob/grasp/wp-admin/admin-header.php line 89).
I need to edit the viewport from my customized plugin. Are there any ideas as to how this might be achieved?
Any code injected by way of the hooks that comply with the hardcoded viewport information has no impact and I can’t see any obtainable hooks contained in the part that happen earlier than the hardcoded information.
