 \begin{eqnarray} 
 a \tag{tag}\\ 
 a \tag{tag}\\ 
 a \tag{tag}\\

Oh wow. 1500 bugs!

It turns out that there were several issues that contributed to this. One was that the heights of the lines were being adjusted to the wrong value (argh). But there were also issues with empty cells (it turns out inline-block nodes with no text content align differently from those with text content), and with nodes whose height is less than the midpoint of the font (didn't appear in your examples, but did in my own tests).

I think I have taken care of all of them in the issue1500 branch of my fork of MathJax.

Well, because pull requests use the same numbers as issues (and we've been using more pull requests lately), there aren't really 1500 bugs. There are 1220 issues (not all of them bugs) and 204 pull requests as of this posting. So I'm not sure what the other items 76 are!

Hm... the numbers I see do add up (maybe you had a filter on?) But yes, over 200 PRs in total -- still awesome :-)
