### Steps to reproduce

when I inserted the latex equation $$ \left| f^{\prime\prime}(x)-f^{\prime\prime}(y) \right| \le M\left| x-y \right|$$, the norm notation “|| ||” about {\prime} disappeared. However, the notation “|| ||” about “x-y” was not disappeared.

### Expected result

The latex code was compiled in TeXstudio. The image shown below was the expected result.

### Actual result

The error result shown below was shown in Obsidian

the notation “|| ||” was disappeared!!!

### Environment

- Operating system: windows 11; Obsidian: v1.0.3
