r=me, good catch :)

Aside: I wonder if maybe this should just be `this.getCachedTreeElement(ancestors[i])`, as there's really no point to walking up the `getParent` chain again since we've already done that.  Tho you might need to duplicate the bit that iterates over `this.children`, but conceptually if we have an item inside `this.children` then it should already be cached.

this should be `return null;` to match the other `return`

Aside: we may also wanna add an early-return above the `while` if `getParent` is NOT provided, as right now it's kinda this silent assumption 😅
