Fix T84701: Popup closes on release while dragging parameter.
Windows Ghost cursor movement was previously changed to use SendInput
because SetCursorPos sporadically allows the cursor to escape the
window. This is now reverted because SendInput causes mouse history via
GetMouseMovePointsEx to contain invalid movement history, likely due to
interaction with mouse acceleration. This resulted in popups closing
when the cursor appeared to leave their range.
