bug#54092: 29.0.50; Org Export ignores subscript/superscript setting in node names

[Philipp Stephani]

Create an Org file like this:

$ cat /tmp/test.org 
#+OPTIONS: ^:{}

* aaa_bbb
:PROPERTIES:
:ALT_TITLE: ccc_ddd
:END:

eee_fff

Visit it in Emacs, enabling Texinfo export:

$ emacs -Q -l org -l ox -l ox-texinfo /tmp/test.org

Export the file to a Texinfo file using C-c C-e i t.
The resulting Texinfo file will contain:


@menu
* ccc@math{_ddd}::
@end menu

@node ccc@math{_ddd}
@chapter aaa_bbb

eee_fff


Note that despite the ^:{} option, the node name (but nothing else)
still (incorrectly) uses a subscript for "ddd".  My suspicion is that
this is due to the use of `org-element-parse-secondary-string' in
`org-export-get-alt-title'; that seems to ignore the export options.

Shouldn't this be reported to the Org bug address instead?
