See the example in the picture:

### DBeaver Version

_No response_

### Steps to reproduce

1. Execute any select in a table
2. Select one column
3. With shift, select a second column
4. The problem is that the last row is not selected.

### Additional context

_No response_

Reproduce the issue in DBeaver 22.2.4 on Windows 10 using any table query, then inspect the result-grid column selection behavior. Done means selecting a second column with Shift also includes the last row, matching the report's screenshot and reproduction steps.
