The change of settings may have affected when a break is due. In particular, `this._breakLastEnd` is modified in `_updateSettings()`, but `this._state` is not modified correspondingly to transition to/from a `BREAK_DUE` state (if appropriate). This could be the cause of the `breakDueAgo should be non-negative` assertion failure from #8280.
