Does cubeide assign the wrong stack size?

When I use CMSIS RTOS I set a stack size of 128 words. Then the following code is generated:

 /* Create the thread(s) */
 
 /* definition and creation of cmdHandlerTask */
 
 const osThreadAttr_t cmdHandlerTask_attributes = {
 
 .name = "cmdHandlerTask",
 
 .priority = (osPriority_t) osPriorityNormal,
 
 .stack_size = 128
 
 };
 
 cmdHandlerTaskHandle = osThreadNew(CmdHandlerTask, NULL, &cmdHandlerTask_attributes);

When I read the documentation, the stack size in osThreadAttr_t is in bytes and the code seems to confirm this. Is this a bug or have I misunderstood it? (Im new to stm32 and this kind of low level programming so Im not too confident that I understood things right.)

Can someone confirm or disprove my suspicion?

Best,
