[BUG] Setting export scope to subtree not working as expected [9.6 (9.6-gb3da42 @ /Users/apc/.emacs.d/straight/build/org/)]

[Alejandro Pérez Carballo]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

Your bug report will be posted to the Org mailing list.

If point is on a heading followed by a subheading without any text in between, 
the export process is using the tree starting with the subheading instead of 
the tree starting from point position. If instead you have some text after the 
first heading and before the subheading, the tree that is exported is the tree 
starting from point position, as expected. I’m assuming this is a bug, but 
maybe I’m missing something.

For example, take a buffer containing just this:

   * The title
   ** A subtitle
   Some text

If I export this to an HTML buffer, with point at the beginning of the first 
line and  after setting the scope to ‘subtree’, I get an HTML buffer whose 
title is “A subtitle”.

If I follow the same steps on a buffer containing just this: 

   * The title
   Some text
   ** A subtitle

I get an HTML buffer whose title is “The title”.

This doesn’t happen with Org 9.5.5. In both cases, I get what I expect, viz. an 
HTML buffer whose title is “The title”.

I can reproduce this with the following minimal configuration:
