It seams that there is an issue with the behavior of `treesit-beginning-of-defun` function in
`c++-ts-mode` when there are static variables present in the source code. For instance, in the
provided code snippet, if the cursor is initially placed on the line containing `int b`, and the
"C-M-a" is pressed, the cursor is positioned on line 4 instead of line 1 where the beginning of
the function is located.

,----
| void func		// c-ts-mode: treesit-beginning-of-defun stops in this line,   RIGHT
| {
|   char * msg;
|   static int a; // c++-ts-mode: treesit-beginning-of-defun stops in this line, WRONG
|   int b;        // PUT CUSOR HERE
| }
`----

it works in c-ts-mode works normally.

Regards.
