1. Click on the _graphs_ hyperlink from a Talos/Raptor alert.
2. Zoom into an area using the upper graph ([can jump directly to this example](https://treeherder.mozilla.org/perf.html#/graphs?timerange=604800&series=mozilla-inbound,2119244,1,1&series=autoland,2119230,1,1&highlightAlerts=1)).
3. Toggle one of the signatures.

Expected:
The gray zoomed in section from upper graph correctly reflects the section from the bottom graph.

What we get instead:
When we toggle off one of the signatures, the upper graph shows the gray zoomed section as applied on the whole graph. When we toggle back on that signature, the upper graph correctly shows that section.
