[kesten_processes] Display of the first equation

[longye-tian]

Hi @mmcky

I noticed a possible rendering issue on the rendered Kesten Processes lecture.

The first displayed equation in the “Kesten processes” section appears slightly clipped at the top in my browser. Here is the screenshot:

I tried both google chrome and microsoft edge and this seems persist.

But when I browse using my phone using safari, it renders fine.

The source equation looks standard, so this might be a site/theme rendering issue rather than a lecture-source issue.

Best,
Longye
