Violations on opening project

When opening a new project, violations are thrown. This is the console readout from opening the project, clicking CONTINUE on the shared user warning, opening a single image resource, and closing the resource dialog.

These violations seem to be in part due to how event listeners and DOM manipulation are handled by the version of the Google Closure library we're using, but it's worth checking to ensure we're following best practices outside of that.
