ControlSend not sending to the non-topmost window - autohotkey

Question

Is it possible to make ControlSend send / click to a background window?
This code finds a window by id / handler, but sends a click / keystroke only if the window is the topmost. ControlSend skips its action if the window is not topmost. ControlClick force brings window to top and then clicks.

PostClick(x,y,win="A") {
lParam := x & 0xFFFF | (y & 0xFFFF) << 16
PostMessage, 0x201, , %lParam%, , %win% ;WM_LBUTTONDOWN
PostMessage, 0x202, , %lParam%, , %win% ;WM_LBUTTONUP
}
RunAsAdmin() {
Loop, %0% {
param := %A_Index% ; Fetch the contents of the variable whose name is contained in A_Index.
params .= A_Space . param
}
ShellExecute := A_IsUnicode ? "shell32\ShellExecute":"shell32\ShellExecuteA"
if not A_IsAdmin

If A_IsCompiled
DllCall(ShellExecute, uint, 0, str, "RunAs", str, A_ScriptFullPath, str, params , str, A_WorkingDir, int, 1)
