Icon size changes may be infrequent but they do happen. It's important that when we resize the panel we don't re-render a tonne of SVGs constantly, we need resizing applets to be smooth.

I don't understand where this blurriness is coming from; that implies we're loading it at a wrong size then resizing; if that's the case, lets fix that rather than hide it.
