[O] Angular brackets break LaTex environment in html-export

[Axel]

Hi,

When I use angular brackets in a LaTeX environment, sometimes they break 
the mathjax-rendering when exported to html/Rhtml (See example below). 
Export into LaTeX-pdf works fine in all cases, but export into html 
fails without whitespaces. Is this due to interference with the 
timestamps in org-mode?

--8<---------------cut here---------------start------------->8---

* heading

\( <R^2> \sim t \)

\( < R^2 > \sim t \)

\[ \left<R^2\right> \sim t \]

\[ \left< R^2 \right> \sim t \]

-8<---------------cut here---------------end------------->8---

Cheers
Axel
