Changing DPI doesn't change the panel width, window caption widths and mouse cursor size

I increased screen resolution 2X. Everything became smaller, as it should be. Then in Settings/Appearance/Fonts I increased DPI 2X. This caused all fonts to become larger, but panel width, window caption widths, and cursor sizes stayed small.

DPI is a general property that affects everything, not just fonts.

Either changing DPI should just affect everything, or there should be a separate "Sizes" tab under Settings/Appearance which would allow to adjust sizes of panel, window captions, cursors, etc.
