Can't sort the "Data Column Binding" table using the column headers

[PedroVitorIPM]

There is a UI inconsistency/regression in the "Edit Data Binding..." dialog window. In older versions of BIRT (up to version 4.4.2), users could click on the column headers (like "Name" or "Expression") to temporarily sort the metadata rows alphabetically or numerically. In newer versions, clicking these headers does nothing.
Interestingly, this sorting functionality still works perfectly in other similar UI contexts, such as the Property Editor -> Binding tab table.

Environment

• OS: Windows
• BIRT Version: 4.21.0
