Bug description

When using mkdocs-material-insiders with mkdocs-static-i18n plugin, there is nondeterministic behavior when navigating to a path which starts with an ISO 3166 country code.

For example, given a path /desktop/ which has other folders/files underneath it--navigating to this link by clicking on the link in the Nav bar from the index sends the user to /de/ (the index for our German translation), instead of to the /desktop/ page in english. Navigating to the /desktop/ page directly, or from any other page, is seemingly unaffected. Reverting to mkdocs-material (not insiders) causes this behavior to not reproduce.
