Setting options in a series without `series.data` is adding default aria-label

[marvin19]

Expected behaviour

I would expect VoiceOver to read the correct aria-label for the series and not create area-label for the empty series (if series is not empty on purpose).

Actual behaviour

When using dashStyle and fetching data with csvURL, VoiceOver tells me that there are 5 lines, but reads out duplicates in this order:

• Series 1, Line 1 of 5 with 0 data points
• Android, Line 1 of 5 with 218 data points
