Description Dirk Fauth CLA 2023-01-11 10:51:46 EST 
When adding the HoverLayer in a header layer stack that also contains the ColumnGroupHeaderLayer or RowGroupHeaderLayer, the hover does not work for the header cells.

The group header cells actually do not support styling for DisplayMode#HOVER or DisplayMode#SELECT. But it should be supported for the header cells that are grouped, meaning the column header cells or row header cells.

There are multiple issues related to this:
- the underlyingToLocal(Column|Row)Position is missing, so events published from the header layers through the group header layer contain untransformed positions in the event.
- getDisplayModeByPosition() does not transform the position correctly when asking the underlying layer
- getConfigLabelsByPosition() does not transform the position correctly when asking the underlying layer
