As discussed in the JBS [issue](https://bugs.openjdk.java.net/browse/JDK-8177945), there are some inconsistencies in the use of `VirtualContainerBase::requestRebuildCells` from `VirtualContainerBase::updateItemCount()`, which is implemented in the different skin classes for virtualised controls `TableViewSkinBase`, `ListViewSkin` or `TreeTableViewSkin`.
The latter already commented out this call (related to JDK-8155798 and JDK-8147483). This PR removes now the calls to `VirtualContainerBase::requestRebuildCells` from `TableViewSkinBase` (except for the case `itemCount = 0` based on JDK-8118897 and JDK-8098235) and `ListViewSkin`. A test is provided for TableView, that verifies that the `selected` pseudo-class state remains set for the selected cell while adding more items. Without this fix, as the cells are rebuilt, the pseudo-class states are clean and set all over again, thus the flickering. For ListView, the test rt_35395 (JDK-8091726) is updated, as now there are way less calls to updateItem. ------------- Commit messages: - Don’t rebuild VirtualFlow cells when TableView/ListView item count changes.
