[IndexTable] Shift key multi-select malfunction in range selection

[tatianau]

Summary

When attempting to use the shift key for multi-selecting items, the feature does not operate as it should. This issue seems to be isolated to the range selection table and does not affect the non-nested index table.

Expected behavior

Users should be able to hold down the shift key and click on items to select multiple entries in a continuous range. This functionality is expected to mimic the behaviour seen in the non-nested index table.

Actual behavior

When users attempt to use the shift key for multi-selecting items in the table with range selection, the feature fails to function correctly. The expected range of items is not selected.
