Long property names are ellipsised and there's no way to see the full name in the Properties tab

Long property names are ellipsised like in the image below and there's no way to see the full name unless the user see the Code. We should allow users to see the full name.
Some ideas:
1. show the full name when the ellipsised name is hovered over

2. allowing drag operation in between the property name and the property value box for adjusting the width of the property name area
