Page title block hidden on custom route, panel or view pages when content type is chosen in block visibility settings

Question

I defined a custom route in a custom module:

mymodule.overviewpage:
  path: '/mymodule-overview'
  defaults:
    _controller: '\Drupal\mymodule\Controller\PageOverviewController::content'
    _title: 'Overview'
  requirements:
    _permission: 'access content'

Here is the controller:

class PageOverviewController  extends ControllerBase {
  public function content() {
    return array(
      '#markup' => 'hello'
    );
  }

}

This route is working fine, I see the "hello" text when entering this path in my project but I do not see the page title. The page title "Overview" is used in the title tag in head of the HTML page but there is no page title block - it is not even rendered. Changing to Bartik theme I see the page title "Overview".

I know found out that the visibility of this block was set: there was a checkbox checked which defined the block to be hidden when on a node page of a special content type/ node bundle:

My question: why is the page title block not visible on panel or view generated pages or on custom routes? What should I add to avoid such a behavior? Is there a way to hide the block for special contenty types without hiding it elsewhere?

Answer 1

Because they are not a page of that node type. This filter doesn't just apply to node/*, it applies to all pages. And if there is no node object, the condition will always be false.

If you need something that is true on all non-node pages but for node pages only for a specific ype, you need to define your own condition plugin or use hook_block_access().
