Bulk-selection interface: Shift-click doesn't select multiple checkboxes #20870

Description

The bulk-selection interface doesn't enable productive bulk selection. When holding Shift and clicking a checkbox that is more than 1 row away, only the clicked checkbox is checked instead of all intervening checkboxes.

Steps to Reproduce

1. Check a checkbox
2. Hold Shift and check another checkbox which is >1 row away

Expected Behavior

• That checkbox, and all intervening checkboxes should be checked, consistent with standard OS UI patterns

Actual Behavior

• Only the clicked checkbox is checked
