History

Prior to March 11, 2021, grabbing the keyboard would always also set the X input focus. Now, it only focuses if it is a non-transient window and otherwise manages the input direction internally.

This means spurious focus/blur events will no longer be sent and the application will not steal focus from other applications (which the window manager may have rejected anyway).
