Compare time periods (% change) to dynamically update within UI when adjusting date range

Description -

I set my panel dates and checked the advanced setting "make date range components relative to panel calendar".

On my table, i right clicked on my custom metric, did "compare time periods" and "custom date range to this date range". 

The new custom date range + percent change metrics are correct at first. 

But when i change the dates on my panel, while i see custom date range metric updating accurately, percent change column always goes to 0%. 

So the custom date range metric will update dynamically but the % change metric will not. 

Why is this feature important to you - This to me seems like a defect and can be confusing for other Adobe users who expect that to change. i had to remove % change column from my dashboard altogether to avoid confusion because changing dates in the dashboard is a common use case for this dashboard.
