Using updateOptions to change the selection of a brush chart doesn't do anything

[jamestjw]

Description

I can't seem to programmatically update the selection area of a brush chart using the updateOptions API

Steps to Reproduce

1. Create a line chart with a brush chart
2. Use updateOptions on the brush chart to modify the selection
3. Brush chart isn't updated (neither is the main chart)

Expected Behavior

updateOptions on the brush chart with a new selection should update the brush chart

Actual Behavior

It just doesn't update anything

The Change selection button calls updateOptions with a new random selection, though it does nothing.

I just had the idea of adding the highlighted part to my example in the reproduction link, and now it works.

Though this is still super odd, I don't see why I need to pass the series again if it hasn't changed?
