Subject: [PATCH] fix: add .fill property to _StripeInsertionRow

_StripeInsertionRow had no .fill property, which causes a failure on
export of a chart that includes subtotals. There is no test that
exercises this case in exporter. Add a test that reproduces this error
in exporter integration tests and add _StripeInsertionRow.fill.
