I did a bit of looking in to this, and may pick it up again soon.

My initial thoughts on an approach:

1. Allow for additional CSS classes to be passed in to FieldLabels during 
construction to set the text size. (Another option might be to create a new 
StyledFieldLabel class, or a setter which triggers a size recalculation)
2. Make the size_.height determined on render_(), same as size._width
3. Alter some of the usages of Blockly.BlockSvg.TITLE_HEIGHT in block_svg.js to 
account for the dynamically determined height

Attached is an example of the layout issue step #3 would need to address.

A different approach to #3 would be to change the text to use 
dominant-baseline: hanging, which would have the text anchored at the top-left 
rather than bottom-left, perhaps not requiring as much change to the svg 
rendering logic. But I'll be targeting IE9 as well which does not support this 
property.

Feel free to make me owner and mark this as an enhancement (I don't think I 
have permissions).
