*Steps to reproduce:*
# Add a new selector in UIBuilder.
# Open/Expand the USS preview panel.
# Expand text properties, right click size and click set as value, notice the USS preview update. 
# Right click align, click set as value. notice the USS preview does not update.

*Actual results:* 

For Text size (and many other properties), Set as value works and the USS code is updated. 

For Align (and many other properties as well), set as value does not work.

*Expected results:* 

Expectation is that "Set as Value" works for all (or all reasonable) properties/styles in the inspector.
