Pull request overview
Fixes DataGrid header-cell hint text so that, when sort indexes are shown and the header is narrow, the tooltip displays the column caption (instead of the sort index text from the hovered indicator element).
Changes:
- Update cell-hint tooltip text selection for header rows to prefer
column.captionover the hovered element’s text. - Add Jest coverage for
cellHintEnabledtooltip behavior (header sort index indicator vs. non-header cells). - Extend the header cell test model to expose the sort-index icon element.
