So does GNOME's default icon theme constrain the icon size to some maximum?

The /usr/share/pixmaps/vim.svg installed by vim-gui-common has a width 
and height of 550pt.  On my system currently, it is shown at a size of 
688x688 pixels by both Nautilus's "Open With" handler and by "Image 
Viewer" (eog).  However the "Open With" tab on Nautilus's file 
"Properties" dialog shows the icon at a small size.  Is the large icon 
shown by the "Open With" handler a bug in Nautilus or some GNOME/GTK+ 
library?

A workaround is to install a GNOME icon theme that includes its own vim 
icon (for example "gnome-colors-common") and select that icon theme in 
the GNOME Tweak Tool.  gnome-colors-common installs a bunch of fixed 
size vim.png icons and a scalable vim.svg (with a size of 48x48 pixels).
