gdb executes expression from hovering over a define (expression) without brackets

Environment

• OS and version: Win11 22H2
• VS Code: 1.92.2
• C/C++ extension: ms-vscode.cpptools
• OS and version of remote machine (if applicable):
• GDB / LLDB version: GNU gdb (Arm GNU Toolchain 13.3.Rel1 (Build arm-13.24)) 14.2.90.20240526-git

Bug Summary and Steps to Reproduce

Bug Summary:
I'm not sure if this is the correct extension for the bug.
It is from an old c-project.

Hovering over a define with an expression, will lead the gdb to execute the expression.
#define LED_ON led = 100
#define LED_OFF led = 0

uint8_t led = 0;

LED_ON;
dely(100);
LED_OFF;

The extension tries to get the value of the define.
But the gdb executes the expression of the define and sets the this value to the memory of the halted microcontroller.

-> =memory-changed,thread-group="i1",addr="0x20010f92",len="0x1"

So i can switch on or off the LED only with hovering over the define.
It is the same with a normal variable.

Additional Information

No response

No source files or tests are named. Start by tracing the hover path that issues the GDB/MI var-create request, then reproduce with the LED_ON and LED_OFF macros on the stated Cortex-M setup. Done means hovering over an expression-valued define or variable no longer changes target memory.
