When the display format of a variable is set to hexadecimal, the context menu for debugging variables is not visible.

Environment

• OS and version: win10
• VS Code: 1.101.1
• C/C++ extension: 1.26.3
• GDB version: 9.2

Bug Summary and Steps to Reproduce

Bug Summary:
When I used -exec set output-radix 16 to change the display format of variables, the context menu for debugging variables disappeared.
However, when I reset its display format to decimal or octal, the Debug Variables context menu returns to normal.

Reproduce the issue in the VS Code C/C++ extension using GDB and the reported -exec set output-radix 16 command. Compare the Debug Variables context menu with decimal or octal output, using the supplied debugger configuration and logs as the starting point. Done means the context menu remains visible when variables are displayed in hexadecimal.
