SVG Images (Ground, Input) become hidden when they become too small (by pressing 'Update Object Scale')

[AlexG1031]

A mechanism's grounded joints gets deleted when you change from one unit to another.

Yeah, I've seen this before. I think when the absolute size of the SVG image becomes too small, the browser tries to optimize but not showing it. I think the solution is to scale everything up by 100 or 1000 so that we have to zoom a significantly for this to happen again. This should be a purely visual bug though so not critical.
