### Issue description

When you create a new scene and type scene name with available translation, the Root Name, which is autocompleted from scene name, will get translated.

When you create the scene, root will have the English name normally.

### Steps to reproduce

0. Make sure you are using non-English language
1. Right click in Filesystem Dock and Create New -> Scene
2. In Scene Name field type something that has available translation
