fix(models): stop the hidden preview renderer from blocking description clicks (#13)

The automatic preview renderer on the model page sits in an invisible box whose
sx width/height of 1 resolve to 100%, so it covers the Description and Tags and
swallows clicks on their links. Let pointer events pass through it.

Fixes #12
