How to simulate mouse drag by win32api.SendMessage in Python?

I try to simulate mouse drag operation by win32api.SendMessage in Python, here is my code:

import win32api
...
lParam_start = win32api.MAKELONG(start[0], start[1])
lParam_end = win32api.MAKELONG(end[0] , end[1])

win32api.SendMessage(self.window.handle, win32con.WM_LBUTTONDOWN, win32con.MK_LBUTTON, lParam_start)
time.sleep(0.1)
win32api.SendMessage(self.window.handle, win32con.WM_MOUSEMOVE, win32con.MK_LBUTTON, lParam_end)
time.sleep(0.1)
win32gui.SendMessage(self.window.handle, win32con.WM_LBUTTONUP, 0, lParam_end)
...

and Spy++ log message:

The actual situation seems to be that the mouse is not in LBUTTONDOWN state during movement.

I have tried replacing WM_LBUTTONUP with WM_MOUSELEAVE, still the same.

How to keep the LBUTTONDOWN state in WM_MOUSEMOVE? I know SendInput() is ok, but it can only be used in foreground mode.
