# LaTex symbol \left| \right| not recongnized in latest OB

### Steps to reproduce

Normally when we want to use (), {} or || to cover the whole equation, we would use \left combined with \right. OB works well when I use it like this.

$$\left( \int_{a}^{b} \right)$$

but in the case |, it just shows nothing, but works well in other markdown editor like Typora or Mark Text.

$$\left| \int_{a}^{b} \right|$$

### Environment

• Operating system: Windows 10 21H2(KB5016688)
• Debug info:

This seems to be a problem with mathjax
https://www.mathjax.org/#demo.

Please, Open a bug report in their github repo.

FWIW both of those work fine here:

• Obsidian 0.15.9
• Installer 0.15.9
• macOS 12.5.1
