Mouse Indicator Does not work on Line Chart with null value in data

Description

The Mouse indicator function does not work on a dojox line chart where a series of data contains a null value. Can you please fix this? The Mouse indicator is a great feature; however, My project heavily relies on dojox line charting where many series contain null values.

Here is a copy/pastable example along with screenshots. Please notice that there is one "null" in the data, and that the mouse indicator works on the left side of the null but fails to work on the right side of the null.

Thank you, Joey
