[jfx19] RFR: 8290348: TreeTableView jumping to top [v2]

[Johan Vos]

> Do not recalculate total estimated size recursively.
> 
> In the (unlikely) event that the recalculation triggers a new recalculation (e.g. when the height of a Cell is changed), do not start this recalculation.
> The cache and cache size may become inconsistent if a recursive calculation is started.
> This fixes JDK-8290348
