Console error when clicking the `.cms-content-header` element

[GuySartorelli]

In /admin/pages if you click the .cms-content-header element (the top area that contains breadcrumbs) but not on an interactive element, a console error occurs. This doesn't appear to have any effect on actual user experience or interaction.

Uncaught TypeError: can't access property "replace", e is undefined
