Comment 7

[Emilio Cobos Álvarez (:emilio)]

Attachment: Bug 1634456 - Use double-raf to wait for caret scrolling to happen.

Before bug 1634153, we were using Dispatch(), so setTimeout(0) was the right
thing to wait for.

In bug 1634153 I used the existing mechanism which works as an early refresh
driver runner, so we need to wait for a refresh driver tick, not an event loop
turn.
