Partial select for tree table

OpenUI5 version:
SAP UI5 version: "1.115.1"

Steps to reproduce the problem:

1. Expand a parent row of a tree table with children.
2. Select a child of a parent row in a tree table.
3. Collapse the child rows so only the parent row is visible.
4. There is no indication that the child inside the parent node is selected.

What is the expected result?
I expect the parent row to be partially selected. The desired behaviour can be observed when using sap.m.Checkbox (Sample: Tri-State Check Box)

What happens instead?
Only the child row is selected. The selection does not have an effect on the parent row selection.
