In markdown hover, hr overlaps following codeblock

[sam-mccall]

Issue Type: Bug

If our LSP server returns the following hover content:

function `x`

---

```cpp
void x();
```

It renders poorly:

No spacing between HR and the code block, and in fact they overlap.
This is due to the negative margin of -6px added by @dbaeumer in 6d83770 to fix other problems in rendering.

Removing that -6px makes it render much better, but presumably breaks other things:

I fixed that a while back ago. Please ping if you are still experiencing this.
