When browsing the documentation (for example: https://bootstrap-vue.js.org/docs/components/table/)
The styling and side pane navigation is completely not working:

Further investigating and I have this console error:

Issue is present in both Chrome & Edge.

UPDATE
Issue only happens if I load my page onto the table documentation (ex: Ctrl + F5 when on the table documentation). If I browse to any other documentation page via navigation on the left, those pages are also not working.
If I reload the page on any other documentation (aside from table), the side pane navigation shows up, and then I can browse to the Table documentation and that shows with no issues.
