Continued fraction, at a certain depth (7 on my machine), seems to make Obsidian crash, though the app doesn’t close completely like a normal crash.

### Steps to reproduce

- Create a new note
- Paste in the following LaTeX code:

```
$$
365 + \cfrac{1}{4+\cfrac{1}{7+\cfrac{1}{1+\cfrac{1}{3+\cfrac{1}{24+\cfrac{1}{6+\cfrac{1}{2}}}}}}}
$$
```

- Switch to preview mode

### Expected result

The expression rendered normally. VSCode renders the same LaTeX fine.

### Actual result

The app “blackout”, i.e. the whole app window turns black, but it doesn’t close. Pressing `Alt+F4` doesn’t close the app either, only Task Manager can.

### Environment

- Operating system: Windows 10

- Obsidian version: v0.12.4

### Additional information

I tried some other expressions and both `\dfrac`

or `\over`

with `\displaystyle`

can crash the app with enough fraction. For example:

```
$$
365 + {1\over \displaystyle 4 + {
1\over\displaystyle 7 + {
1\over\displaystyle 1 + {
1\over\displaystyle 3 + {
1\over\displaystyle 24 + {
1\over\displaystyle 6 + {
1\over\displaystyle 2 + {
1\over\displaystyle 2 + \cdots
}}}}}}}}
$$
```
