Ah. This is annoying, for you and for me.

Thank you.

As you noticed, using Org Element is a no-go, unfortunately. Parsing an
element is a O(N) operation by the number of elements before it in
a section. In particular, it is not bounded, and not mitigated by
a cache. For large documents, it is going to be unbearably slow, too.
I don't think the solution is to use combine-after-change-calls either,
because even a single call to `org-element-at-point' can be noticeable
in a very large section. Such low-level code should avoid using the
Element library altogether, except for the initial folding part, which
is interactive.
If you use modification-hooks and al., you don't need to parse anything,
because you can store information as text properties. Therefore, once
the modification happens, you already know where you are (or, at least
where you were before the change).
The ideas I suggested about sensitive parts of elements are worth
exploring, IMO. Do you have any issue with them?

I already specified what parts were "sensitive" in a previous message.

`org-element-at-point' is local, `org-element-parse-buffer' is global.
They are not equivalent, but is it an issue?
