[lambry]

Motivation and Context

JIRA issue: https://digital-vic.atlassian.net/browse/SDPAP-7958

Changed

1. Any in page nav item that started with a number would break the page once clicked and refreshed, shared or opened in a new tab (on solar vic), this was due to the fact that IDs starting with a numbers make for an invalid selectors
