Transitions apply185 // to this case. If none is defined, JND is used instead.186 //187 // If we're already showing a fallback and it gets "retried", allowing us to show188 // another level, but there's still an inner boundary that would show a fallback,189 // then we suspend/restart for 500ms since the last time we showed a fallback190 // anywhere in the tree. This effectively throttles progressive loading into a191 // consistent train of commits. This also gives us an opportunity to restart to192 // get to the completed state slightly earlier.193 //194 // If there's ambiguity due to batching it's resolved in preference of:195 // 1) "delayed", 2) "initial render", 3) "retry".196 //197 // We want to ensure that a "busy" state doesn't get force committed.
