What does the pull request do?
This PR fixes issue 14737 #14737 by retaining the current selection when selecting a range of rows in DataGrid.
What is the current behavior?
Currently non-consecutive blocks can not be selected because the current selection is cleared when a range is being selected.
What is the updated/expected behavior with this PR?
Removed the call to ClearRowSelection when the DataGridSelectionAction is SelectFromAnchorToCurrent. The logic for selection is already robust to this change i.e. can select ranges forward/backward, cover existing selections, add new items to existing selection etc.
How was the solution implemented (if it's not obvious)?
Removed a single method call.
Checklist
Would like some advice on how to approach unit testing. This doesn't look like it impacts on documentation.
