Social channels, Theme Switcher, Search, Ask AI are unresponsive / not clickable in error 404 pages

Those buttons in the header are unresponsive / not clickable in the 404 pages:

They're working fine in status 200 pages

This pages are returning 404 for me:
https://tanstack.com/form/latest/docs/reference/index
https://tanstack.com/db/latest/docs/reference/index

Just visit them, check if they're returning 404 and try to click the buttons on the header...

When I created the issue, the buttons were failing for me 100% of the time while in a 404 page, no matter what.

But this morning I went to https://tanstack.com/form/latest, then I clicked the API link in the "sub header" bar, it still returns 404, but the Social channels, Theme Switcher, Search, Ask AI buttons are working.

If I refresh the 404 page, they stop working again.

When logged in, with github account, I see the buttons behavior is basically the same. But the "Login" button is still there (It should be rendering the user avatar with the user menu)

So I thought... Maybe Is just my browser cache and you have a special talent to mess with these kind of things 😅 So I've created an incognito session, I have duplicated the tab and split into two windows, I have logged into with my github account and then, refreshed the other window with F5 and CTRL + F5, navigated to https://tanstack.com/form/latest, then I clicked the API link again and the "Login" button is still there...

The login button is rendered even while in https://tanstack.com/account while logged in, after a refresh
