Make dialog windows get focus

I’m using LibreOffice Calc (Version: 4.4.5.2).

I saw that various dialog windows (but not all) mostly did not get focus when they opened. I needed to alt+tab them or to mouse-click within the dialog window.

Then I came across an answer which entails setting Tools > Options > View > Mouse > Mouse positioning to "Dialog center". That works perfectly for me.

But why does it work? Does Mouse positioning to “Dialog center” incorporate a “click” to make the dialog window active? And shouldn’t the default be to have a dialog window in focus as soon as it opens?

See about upgrading to 5.0.0, or specifically 5.0.0 RC5 which is the same as the Fresh 5.0.0.
