Bug: Filename rendering is cut off in project

Hi! Just a quick bug report.

I went to remix Mary Rose Cook’s “circles bouncing off lines” project and I noticed that in the filename panel, the javascript filename was cut off. The tooltip renders it correctly but the listing doesn’t, so I was confused for a minute trying to find the actual JS file since the extension was missing.

This is on Chrome 56.0.2924.87 / OSX.
