Indices of square brackets break expressions

For example $$\mathbb{E}[\Delta \theta^2 ]t$$ $$\mathbb{E}[\Delta \theta^2]{t - 1}$$

It's a limitation of adding math in as a post-processing step on Github -- it's due to the processing of underline as part of Markdown for italicized text. If you escape the underlines with a slash, i.e. \_, then it does work. As example if you use the following code instead:

$$\mathop{\mathbb{E}}[\Delta \theta^2 ]\_t$$
$$E[\Delta \theta^2]\_{t - 1}$$

then you get:

$$\mathop{\mathbb{E}}[\Delta \theta^2 ]_t$$ $$E[\Delta \theta^2]_{t - 1}$$

Oh, thanks, i've got it! When i was writing that issue, I mention that if equations was delimited by new line, then escaping underscore is not even needed.

$$\mathbb{E}[\Delta \theta^2 ]_t$$

$$\mathbb{E}[\Delta \theta^2]_{t - 1}$$
