LaTeX commands to type > (greater than) and < (less than) in KaTeX - youtrack

Question

Youtrack and many other web apps use KaTeX to render mathematical notation and markdown for all other things.
However markdown parser treats certain characters in a special way and interferes with KaTeX.
For example the following equation
\begin{equation}
X_i = \begin{cases}
0, t_i < t_{i-1} \\
1, (t_i - t_{i-1}) > t_0 \\
X_{i-1}, otherwise
\end{cases}
\end{equation}
Would render incorrectly as
Note the missing line.
The reason is that < and > and the text between are treated as an HTML tag and thus ignored.
The intended rendering would instead look like
Reordering the cases resolves the issue as well as replacing < with \leq and > with \geq. But both solutions seem incomplete and in the latter case change the meaning of the equation.
In LaTeX there are no predefined commands for < and > and KaTeX currently does not support \newcommand yet.

Answer 1

I have posted a similar question on tex stackexchange. And while it was closed there as off-topic, users provided a solution in comments. Using \lt for < and \gt for > is supported in KaTeX. So the equation should be typed as
\begin{equation}
X_i = \begin{cases}
0, t_i \lt t_{i-1} \\
1, (t_i - t_{i-1}) \gt t_0 \\
X_{i-1}, otherwise
\end{cases}
\end{equation}
