The patch also revealed an idea for another test.  The new test is
revealing existing bug on master.  Attached is the patch adding the test
with ":expected-result :failed".

Subject: [PATCH] Add a test for known bug in org-element-cache

* testing/lisp/test-org-element.el (test-org-element/cache-bugs): A
new test documenting a known bug:

1. Create initial file like:

P0

  P1
  | a | b |
<point>| c | d |

Note that second line of the table is not indented.  Now,
org-element-at-point returns table-row.

2. Modify the file to test org-element-cache

P0

- item

  P1
  | a | b |
<point>| c | d |

Now, the first (indented) row of the table belongs to item.  The
second row should be an individual table and org-element-at-point
returns table.
