Select next/prev does not always select the expected note

[viddo]

Steps to reproduce

1. Open first three notes (i.e. select, focus on editor to open text editor)
2. Click on the first note (should now be selected)
3. ↓ three times "quickly" -- but not too quickly, ~10-50ms

Expected behavior:

Should preview the 3rd note

Actual behavior:

Previewing the 2rd note

Investigation

It appears to be some kind of race condition related to selection and the https://github.com/viddo/atom-textual-velocity/blob/bb2ba0147866aaf05acac89a43b78c4d8f1d99e9/lib/epics/active-pane-item.js epic which observes the pane changes. For some reason it triggers an event for the 2nd pane item even though in theory it should be debounced when the 3rd item is selected.
