Describe the bug
Vectors from point A to B are typically listed as AB with an arrow over the top, like in this image from a textbook:

I am trying to specify this vector using $\vec{AB}$. In most cases the arrow is getting cut off so only a small dot appears above the letters:

If the letters are below another row of text the arrows appear nicely. If I try to replicate this effect by specifying a new line in front of the vector, the whole text is shuffled down an look out of line.
The hint:
[FormulaText(@"$\ \vec{OB}$ is the vector followed to get from the origin $O$ to point $A$."); FormulaText(@"If $\vec{AB}=\bf{a}$, $\vec{BA}=\bf{-a}$.") ],
shows up as:

I can't find a way to get the arrow to show up consistently while keeping all of the text in line.
