Export Spreadsheet as csv with code to produce svg chart includes the svg output tags in the csv cell instead of the tiki syntax to generate the chart

Reproduced when attempting to export sheet4 in doc.t.o, which is part of the sample charts generated from the tiki spreadsheet feature:
https://doc.tiki.org/tiki-export_sheet.php?sheetId=4

When exported (as csv with comma, and utf8) the content is like:

Chart Type,Example,Chart,Data,Month,Year
Vertical Bar,"=BARCHART(D2:D13),<div class="jSheetChart"><svg height="172" width="421" version="1.1" xmlns="http://www.w3.org/2000/svg"><desc>Created with Raphaël</desc><defs></defs><path d="M80,139L58,139L58,127L80,127Z" stroke="none" fill="#1751a7"></path><path d="M108,139L86,139L86,1,4,Jan,2001

And in my honest opinion, it should be something like:

Chart Type,Example,Chart,Data,Month,Year
Vertical Bar,"=BARCHART(D2:D13)",=BARCHART(D2:D13),4,Jan,2001
Horizontal Bar,"=HBARCHART(D2:D13)",=HBARCHART(D2:D13),6,Feb,2002
Line,"=LINECHART(D2:D8, F2:F6)",=LINECHART(D2:D8, F2:F6),7.2,Mar,2003
Pie,"=PIECHART(D2:D8, E2:E8)",=PIECHART(D2:D8, E2:E8),7.5,Apr,2004
