Issue with "Key Values": table of contents overlaps with page content

MDN URL: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values

What information was incorrect, unhelpful, or incomplete?

Information itself was OK. The page layout is just completely broken. There’s a lot of empty space on the left, whereas the page requires sideways scrolling to see the full tables, and the tables overlap with the table of contents. If it helps, I viewed it on a screen where the CSS pixel size of the window was 1368x800, and the problem seems to present itself when the screen CSS width is above 1200px.

Screen recordings of the isssue:

Specific section or headline?

Every section.

What did you expect to see?

A correctly formatted page

Did you test this? If so, how?

The sidebar is also missing on the KeyboardEvent: code values article:

$ grep --include='*.md' -irL 'ApiRef' files/en-us/web/api/keyboardevent        
files/en-us/web/api/keyboardevent/code/code_values/index.md
files/en-us/web/api/keyboardevent/key/key_values/index.md

Probably the reason for this is that the these two articles are “just” lists related to the KeyboardEvent, but they don’t directly document a part of the API (and are therefore not linked in KeyboardEvent sidebar). 🤔

Anyways, I created https://github.com/mdn/content/issues/13761 to track this, because adding a sidebar there doesn’t fix the reported layout problem.

As for the empty space on the left, I believe we are missing a sidebar (menu) there. (@dipikabh Is the missing sidebar here part of the issue you’re currently investigating/working on?)

Yes, it is related but not the same issue I guess. But it is definitely the same macro that generates the sidebar - the macro call seems to be missing on this page.
