Last row is removed on export if table has groupheaders

[jules1091]

I have a table with groupheaders like it is implemented in this example:
https://stackblitz.com/edit/angular-mattable-with-groupheader?file=app/table-basic-example.html

If I export this table as .csv the last row is removed from the table and not shown in the .csv file.

I planned on using groupBy with the mat exporter and saw this issue I decided to check myself if it was still the case.

I created a stackblitz to play around with. I used demo that is provided for mat table exporter and changed the table with the one that @jules1091 provided, when I click on CSV and open the file to me it seems that every row is there.

If I understood correctly the issue, the row with the data from the Oxygen element should not be there, but in reality when I open the file everything looks good to me

The exported file contains all rows but after the download is finished, the last row (normal row, not the grouping one) in my view disappears.

Uhm, I implemented the groupBy also on my end and when i export the file, and I checked every row in the mat-table with the excel file and on my end every row in the view is there.

I decided to go back on the stack blitz, and If I understand correctly when I press the export button and wait for the download to finish the oxygen row should disappear from the table but it's still there.
