Following my own advice, I find that

  \documentclass{article}
  \begin{document}

  $\overrightarrow{AB}+\overrightarrow{BC}=\overrightarrow{AC}$

  \end{document}

demonstrates the issue. And I agree that it's a valid issue. The
current incarnation of arrows in LaTeX is a disaster. I always use
arrows from the picture environment to avoid them.

If you want to stick with conventional LaTeX arrows, a workaround 
is to insert struts:

$\overrightarrow{\strut AB}+\overrightarrow{\strut BC}=\overrightarrow{\strut AC}$
