Rebase actions after receiving changes by the server

onReceive.ts

  onReceive(change: Change) {
    this.confirmedState = {
      id: change.changeId,
      state: applyPatches(this.confirmedState.state, change.patches)
    };
    // reapply all the pending actions, filter out the ones that can't be applied anymore
    const { pendingActions } = this;
    // reset the pending changes collection. We will fill it again by replaying all actions.
    this.pendingActions = [];
    this.currentState = this.confirmedState.state;

    let p;
    while ((p = pendingActions.shift())) {
      try {
        this.propose(p.fn);
      } catch (e) {
        console.warn(
          `Dropped change ${p.id}, it could not be applied anymore: ${e}`
        );
      }
    }
