[Bug] Inheritdoc Rendering Isssue in Sections

**Describe the bug**
I have noticed that every time when I use a `` within a `` section, the rendered output looks off. I will give an example for how to reproduce this problem with a remarks reference, but there are also other cases where `inheritdoc` fails to render the output properly in DocFx (cf. Context, Exhibit 2).

**To Reproduce**
Steps to reproduce the behavior:
1. Decorate a function `Foo` with a doc string, and include a `` section

```csharp
///
/// Foo.
///
///
/// Hello World!.
///
public void Foo() => throw new NotImplementedException();
```

2. Reference the remark from `Foo` in `Bar`:

```csharp
///
/// Bar.
///
///
///
///
public void Bar() => throw new NotImplementedException();
```

**Expected behavior**

The output should look like this:

### Remarks

Hello World!.

---

But instead, it comes out like this:

### Remarks

```

Hello World!.
```

**Context (please complete the following information):**
- OS: Windows
- Docfx version: 2.78.4

**Additional context**
Here are some screen shots from a real world application:

**Exhibit 1**

**Exhibit 2**

where I used something like

```csharp
///
///
///
```
