New description:
As the title indicates, HTML substring search fails to find matches in the
haystack if the needle consists of multiple sibling elements that do
appear in the haystack with more siblings on the same level.
This is a follow-up to #24112, which fixed the simple case when the list
of children of an element matches exactly the list of children of the
needle.
A simple, but somewhat sub-optimal solution could be to use two nested
loops to compare the children of `self` with the children of the root
element; an optimal, but much more complex solution would be to implement
a variant of KMP on the children of `self`.
