Many applications, above all graphic ones, manage mouse zooming so that zooming occurs in such a way that the document position where the mouse is placed remains in the same place. Nowadays libreoffice's zooming with mouse works expanding the document independently of mouse position, so that, the place where the mouse goes out of screen if the mouse is on a side of the document.
I agree. Just now I was working on Draw, and it is very annoying when you want to zoom a specific region of your document, and that regions disappears from your front.
