Fix tabs if deep-linked to non-tab anchor

[MattIPv4]

Description

If a user deep-linked to an anchor on the page that wasn't a tab, the tabs would all hide themselves. This fixes that.

Test process

Go to /details#spam, observe tabs are still visible.

Go to /details#companies, observe correct tab is shown.
