Child questions of grouped sections within repeating sections not ignored during CSV export

Problem description

During a CSV export, if a question is a child of a grouped section that is a child of a repeating section, the question is not ignored during the export and the question is included in the CSV header columns.

Expected behavior

The question should be ignored from the CSV header columns as the question is already present as part of the indexed column headers

Steps to reproduce the behavior

1. Make submissions to an XLSForm that has grouped section inside a repeating section. Here is an example
   multiples-group-repeat.xlsx
2. Export the CSV data without splitting select multiples. Check the header columns will match the following name, age, grp1/grp2/browser_use[1]/grp3/grp4/grp5/year, grp1/grp2/browser_use[1]/grp3/grp4/grp5/browsers, grp1/grp2/browser_use[2]/grp3/grp4/grp5/year, grp1/grp2/browser_use[2]/grp3/grp4/grp5/browsers, grp1/grp2/browser_use/grp3/grp4/grp5/year, grp1/grp2/browser_use/grp3/grp4/grp5/browsers...
3. The correct header columns should be name, age, grp1/grp2/browser_use[1]/grp3/grp4/grp5/year, grp1/grp2/browser_use[1]/grp3/grp4/grp5/browsers, grp1/grp2/browser_use[2]/grp3/grp4/grp5/year, grp1/grp2/browser_use[2]/grp3/grp4/grp5/browsers...
4. Now export the CSV data with split select multiples. The out come should be similar where the non-indexed repeat question columns are included
