Step components from ProgressTracker inaccurate

Issue can be replicated on Chrome; after navigating to a page within the Windfall Elimination web app, if a user copies the current URL into a new tab, the "status" of some StyledStep components (e.g. "complete", "active", "ongoing") becomes inaccurate.

Reproduce the issue in Chrome by opening a page in the Windfall Elimination web app, copying its URL into a new tab, and checking the ProgressTracker StyledStep statuses. Trace how the current URL determines the step state, then verify that statuses such as complete, active, and ongoing remain accurate after direct navigation.
