Cannot print page title in page.html.twig The following line in page.html.twig does not print the page title:

&lt;h1&gt;{{ title }}&lt;/h1&gt;


The page title outputs using the Page title block, but not this piece of template code. I found the title variable in the documentation commented out at the top of page.html.twig. Does this code need to be wrapped in something else?
The variable {{ title }} is only used in maintenance and install pages where blocks are not available. See the change record https://www.drupal.org/node/2568563
