backward-sexp throws scan-error "Unbalanced parentheses", but forward-sexp works

[ndame]

I sometimes run into the situation with huge elisp lists, that I cannot use 
backward-sexp, because it throws an error, but forward-sexp works on the same 
list. Then, after a while it fixes itself without changing the buffer and 
backwards-sexp works too. I suspect scrolling through the file fixes it, so it 
might be connected to fontification? Though it's just a guess, I don't see how 
they could be related.

Is there a known situation when the same elisp list can be navigated forward, 
but not backward?

I'm on Emacs 27.1. Was there a related bug fixed in 28?

I cannot yet replicate the problem knowingly, it just occurs every once in a 
while.
