Opening source view using context menu does not always seek to the right line

This is a problem because the selected call node influences the behavior of the source view in that it determines which line is scrolled into view. You can see this in [this profile in the deploy preview](https://deploy-preview-4423--perf-html.netlify.app/public/t1xfb8zn0181gg2zyjeyk7j7tkdhgwhjnvxfn18/calltree/?globalTrackOrder=0w7&hiddenGlobalTracks=1w7&hiddenLocalTracksByPid=354293-0wu~354382-0~354527-0~354609-0~354426-0~354405-0~354531-0&profileName=Firefox%20110%E2%80%93%20Linux&range=3353m145&thread=0&transforms=f-combined-0wacB2B3ghz9jC2C5&v=8) as follows:

> 1. Select the call node with the function "js::gc::GCRuntime::gcSlice".
>
> 2. Right click the call node with the function "js::gc::GCRuntime::markUntilBudgetExhausted" (6 frames deeper than the selected call node). Both these functions are located in GC.cpp.

> 3. Click "Show GC.cpp".

> Now the source view will show GC.cpp, but it will be scrolled to display the contents of the "js::gc::GCRuntime::gcSlice" function. Ideally, it would be scrolled to display the contents of the "markUntilBudgetExhausted" function.
