About window moves on Details click

[topeterk]

After opening of the About window, when it gets moved around manually and then the Details button is pressed, the window jumps back to its original (CenterParent) position. This feels very non-intuitive to me, as I just expect the window to grow.
As @Hofknecht mentioned to me that it may was because when clicking on SystemInfo button the new window with the system's information is also placed at the same location but it isn't, it may even popup on a different monitor. So from my side, there is no reason to move the window when details shall be shown.
