Total nit: would something like "forceLTR" be a better name for this property? 
If we're in the UI layer, should we name things after high-level concepts like
"this is a URL", or should we name them after what they do, like "this forces
the text to display LTR"?

Your suggestion makes sense but I'm interested in moving the blue text styling
for URLs into this class as well so I chose the more semantic name.
