      Note: the fix has been successfully tested on learn.moodle.net during the peer-review

      To test this, you need a custom theme that uses the Boost as the parent theme. Your theme should not define its layouts (or not all of them at least). Instead, it should simply rely on the parent to provide their full list. https://moodle.org/plugins/theme_photo is an example of such a theme.

      Without this fix, such a theme will not simply work and will display the reported errors.

      With the fix, the theme should work again.

      Description

      The site learn.moodle.net uses a custom theme which is a child theme of the Boost. After upgrading the site to 3.7, it stopped working with error messages like

      Invalid page layout specified: login

      or

      Undefined index: standard in lib/outputlib.php on line 2464

      These are layouts provided by the boost's config file. Our custom theme only defines its own frontpage layout. All others are supposed to be inherited.

      It turned out to be a regression of MDL-64506 - the commit e00f1c663c1 changed the way how theme_config::__construct() sets the $baseconfig - before, it was always the bootstrapbase - so it loaded all its layouts etc. But now, we do not use it.
