The dynamic_tabs module does not update the page title when changing tabs. This is true even if you refresh the page, because the selected tab is loaded by JavaScript code using the anchor part of the URL.

To resolve this, we need a JS module to dynamically change titles. We must define how a title is structured to allow manipulating specific parts. When a tab is selected, it should be possible to swap the old tab name with the new. It should not be the responsibility of dynamic_tabs to completely rewrite the title. That will lead to inconsistency issues as we already have enough of.
