Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket):

When I create my own route, the Breadcrumbs are not cleared

Steps to reproduce (Required on creation):

• add the attached custom script plugin.js to cockpit (copy to webappc/scripts folder and add to config.js)
• navigate to the processes dashboard
• Change to URL to #/path

Observed Behavior (Required on creation):

• The Breadcrumbs show Processes

Expected behavior (Required on creation):

• No breadcrumbs are shown

Root Cause (Required on prioritization):

• The root angular widget is configured with $scope.$root.showBreadcrumbs, which is not changed in custom plugins

Solution Ideas (Optional):

• Always set it to false for custom routes
