What steps will reproduce the problem?
(1) Record a trace and wait for it to be displayed.
(2) Select a region of tracing so that slices are displayed at the bottom
(3) Click on any slice name - this displays a new UI with histograms by CPU Duration, Duration, Self Time, etc
(4) Switch type of histogram a few times
(5) Click at the horizontal divider below the histogram and drag it down
(6) Click on any histogram bar to show a subset of events below the horizontal divider

What is the expected result?
Expect only one histogram to be shown at the time and expect the UI to look nice.

What happens instead?
Histograms keep getting added below each other every time I switch from one histogram to another, for example from CPU Duration to Duration.
And histograms end up overlapping the table showing event instances.
See the attached picture.
