Invalid viewBox for element preview dropdown SVG

The viewBox attribute on the SVG element of the element preview dropdown used in the elements navigation has an invalid viewBox, set to -Infinity -Infinity Infinity Infinity, which causes the SVG to not be resized at all to fit the dropdown, so only the first 100 pixels or so on the top-left corner are visible.
