Discover "Top 5" should remain visible when selecting "filter out"

[edmacdonald]

When viewing data in the discover tab, it is convenient to filter out records using the "top 5" pop up. I find I frequently want to filter out several of the top values to "zero in" on the data I'm interested in. It used to be that the pop up would remain in place while selecting these, and the top 5 would be updated each time - very convenient. Now the dialog disappears each time a value is selected requiring the dialog to be re-opened each time.
