Right click > Move on windows title bar does not fully work as expected (arrow do no move)

reactos-bootcd-0.4.15-dev-7848-ga68406b-x86-gcc-lin-dbg

• Open any window (Explorer, Notepad....)
• Right click on Title bar, select "Move"

• Cursor is moved to the center of the title bar
• Unable to move window with keyboard arrows
• Expected result : Up/Down/Left/Right arrow to move the window position (and once an arrow is pressed, the window should be "attached" to the cursor position, like if left mouse button was held down)
• Nothing logged on such action.
