Bug: redundant and undocumented #label is required to link to a table [9

From: James Powell
Subject: Bug: redundant and undocumented #label is required to link to a table [9.4.4 (9.4.4-dist @ /home/powellj/elisp/org-9.4.4/lisp/)]
Date: Mon, 19 Apr 2021 10:18:26 -0700
User-agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Thunderbird/68.12.0

Using Org mode version 9.4.4 I build this document:

#+NAME: t1
#+begin_src R :exports both
  x <- tribble(~a, ~b, 1, 3)
#+CAPTION: Org Table
| 1 | 3 |

I want to refer to Table [[t1]].

What I expect: the latex export will include the table and link to it.

What happens instead: the code and table appear, numbered and captioned.
However, the link is broken ("I want to refer to Table ??"). Looking in
the latex, this line reads

> I want to refer to Table \ref{org993764c}.

but that label org993764c appears nowhere else in the file.

Org-lint doesn't complain about the file at all.  I posted this
earlier to this list and learned about a workaround

" It works if you put a #+label on the table ... which confuses me,
because I looked through the manual for #+label and there's no mention
of it at all, but a bunch of my Org files use it (for LaTeX export). "

(William Denton writing in

As another workaround, the snippet as written (with no #+label) works
if you export to html instead of latex.
