Test wrong formatting from new editor:

Single line

`
```
const hello = "world";
```
`

Multi line

`
```
const hello = "world";

const foo = 42;

console.log(hello, foo);
```
`



Single line more backticks

`
`````
const hello = "world";
`````
`

Multi line more backticks

`
```
const hello = "world";

const foo = 42;

console.log(hello, foo);
```
