This is actually what is happening, when we scroll down and find a TreeCell that has a disclosure node this is when the condition `disclosureWidth > defaultDisclosureWidth` is true and we do a re-layout of the visible previous cells before the disclosure node and the new value is saved in the `maxDisclosureWidthMap` so the cells that are layouted after the disclosure node when scrolling are using the new value of `defaultDisclosureWidth`.
