Identity filter with blank values

Hi there,

I'm using the latest identity filter (https://learn.microsoft.com/en-us/power-bi/developer/visuals/identity-filter-api) but I found that it doesn't work well with null values.

For example, in the following scenario, I set up an identity filter with a datapoint with a null value:

The problem is that the filter applies to all data point with a null value, not just the selected one:

Any suggestions?

Thanks!
