Don't activate MSW dialogs when setting their initial size.

As the dialog is not shown yet at this moment, activating it didn't work
correctly and the dialog didn't get the focus when it was shown later.
Fix this by preventing ::SetWindowPos() from activating it, which it does by
default.

Closes #13765.
