closes#4140
The bare-numeric-text heuristic added in #3894 to detect non-superscript
footnotes (`/^.{0,2}\d+$/` over `anchor.textContent`) was too permissive:
in-book TOCs that list chapter/verse links such as `<a>1</a>, <a>2</a>, ...`
all match the regex, so clicking them sets `check=true` and the footnote
handler renders the destination as a popup instead of letting the link
navigate. The OSB v2 verse-index and OSB v4 chapter-index from the bug
report both hit this.
Reject the `check` heuristic when the clicked link sits inside a numeric
link list (2+ sibling links with the same short-numeric pattern within
three ancestor levels). A real body paragraph with a couple of footnote
markers still passes; a flat TOC of numeric links does not.
