Take your favorite Sage worksheet. Go into TinyMCE. Write a long
sentence, preferably one that has a long sequence of formulas like $
\sum_{i=1}^{k+1} i=\sum_{i=1}^k i+(k+1)=\frac{k(k+1)}{2}+(k+1)=(k
+1)\left(\frac{k}{2}+1\right)=\frac{(k+1)(k+2)}{2},$, and make sure to
put the formulas in such a place that the formula is toward the end of
a line once you finish the text cell.
You will see that the jsmath rendering will not split the LaTeX across
lines, which we know. But rather than going to the *next* line and
just leaving an empty space on the right of the first line, it keeps
an overflow on the first line, and then leaves a corresponding empty
space on the *left* of the second line.
It's actually a little fun to zoom in and out if your browser supports
that, but really, really annoying to have it happen in class.
Especially on the first day, when you're trying to show how convenient
Sage is. (It's not as bad as the 'mysterious moving text' bug, of
course.)
So will upgrading to MathJax fix this? I realize that $$...$$ is a
workaround, but in the long run that is not always the best way to
incorporate medium-length formulas - because it all depends on where
the line ends in the font size.
I understand that it probably can never be smart enough to do line
breaks like "real" LaTeX, but at least it would be nice for it to
compute whether there is enough space left in the browser window and
move to the next line if not.
Thanks!
