Multi-select range selection leaves hidden children of last row in range unselected.

[lbwexler]

Doing multi-select range selection on tree data will leave the hidden children of the last row in your range unselected. This is built-in behavior of ag-Grid, and not entirely clear that it is a bug, but it can be confusing to users.

Would like to be able to implement a hoist workaround. Perhaps recognize the presence of a range with all children, and include the "tailing" hidden children? Alternatively, would it be useful to have a mode in which hidden children were always included in any selection?
