Comment (by adamsilverstein):

 In [attachment:37313.diff] :
 * Add a `debouncedScrollHandler` in `editor-expand.js`
 * Use Underscore `_.debounce` in favor of `setTimeout` and `afterScroll`
 events

 @ericlewis can you test this to see if it resolves the issue for you?

 The flicker is caused by a secondary call to `adjust` in `afterScroll.` -
 the right bar gets pinned, then unpinned or the other way around,
 repeatedly.

 My only concern here is that `afterScroll` was added to handle some edge
 case, maybe @azaozz
 or @iseulde can tell us?
