I think this should be child->title() or child->accessibilityDescription() or
something else that calls textUnderElement indirectly but also respects
aria-label, etc.

For example:

<figure>
  <figcaption aria-label="Alternate caption">Original caption</figcaption>
</figure>

Alternatively, this should be done in accessibilityDescription - i.e. leave this
code correct for title() but have accessibilityDescription check the figcaption.

Thanks for your idea.
I took the 2nd suggestion because I think it's better to keep consistency for
functions.
I updated patchset and I verified that I can get "Alternate caption" for name on
Windows with example below.
Could you take a look at the 2nd patchset?
