Why is "Patient ID" underlined in the UI?

When viewing a patient profile in OpenMRS 2.0, in the header, “Patient ID” is underlined, just like “Person, Test”:

It seems like there could be some UI consistency improved here. Underlining a variable such as the patient’s name makes perfect sense, just like a paper form. However, “Patient ID” won’t be changing. If anything, the ID itself should be underlined if not in the oval. Or, even better, the oval should be underlined with “Patient ID” caption, just like “surname” or “name” for the patient name.
