When navigating gated content, the previous and next buttons stop working

[mariajgrimaldi]

Description

When navigating gated content, the previous and next buttons stop working so the user can't go to previous/next subsections.

Expected behavior

As a learner, upon navigating to a gated unit, you should see a message about completing the prerequisite, and both the "Previous" and "Next" buttons should function correctly.

Actual behavior

As a learner, when you navigate to a gated unit, you see the message prompting you to complete the prerequisite, but the "Previous" and "Next" buttons do not work.

Steps to reproduce

1. Log in as a learner and navigate to a unit that is gated by the prerequisite.
2. Observe the message about completing the prerequisite and attempt to use the "Previous" and "Next" buttons.

I could reproduce this after doing the following:

1. Configuring a subsection as a prerequisite
2. Making that subsection the prerequisite of another subsection
3. Go to the prerequisite subsection and navigate to the gated subsection
4. If I try to go to the previous unit right before the gated subsection, the sequence buttons stop working for some reason
5. If from the sidebar I try entering one of the units in the gated subsection, and the previous button works

Does this relate to #1429 at all?

@bradenmacdonald: I'm not sure, but I asked my team for help looking into it. Hopefully, they'll have some ideas soon.
