This reverts commit c19fbe86dd.
Reason: timeouts while doing hot reload in hot_mode_dev_cycle__preview_dart_2_benchmark.
It seems that setTraversalBefore doesn't work as well as setTraversalAfter for some reason, although I'm using them the same way. Some apps would lock up TalkBack when traversing if setTraversalBefore was set, but not with the equivalent setTraversalAfter.
It's not entirely clear why this is, but I'm going with this to at least get it fixed for apps we know about.
