Copying Variables/Expressions Copies Entire Row Leading to Incorrect Pasting

[SougandhS]

In the Eclipse Debug view (Variables and Expressions tabs), performing a copy action on a variable or expression currently copies the entire row content. This includes multiple columns such as Name, Value, Type, and any other visible columns. This behavior leads to inconsistent and sometimes incorrect results when pasting the copied content. In most cases, users expect only the Name (Expression or Variable) to be copied, but instead, the combined row text is placed on the clipboard.

eg.

Copying args will copy -> args String[0] (id=22) String[] to the clipboard
