Description
As seen in MemoryManager<T> from System.Memory in dotnet/runtime, some <remarks> sections are getting produced with invalid structure, and duplicated content.
From `MemoryManager`1.xml`
<Docs>
<typeparam name="T">The type of items in the memory buffer managed by this memory manager.</typeparam>
<summary>An abstract base class that is used to replace the implementation of <see cref="T:System.Memory`1" />.</summary>
<remarks>
<format type="text/markdown"><![CDATA[
The `MemoryManager<T>` class is used to extend the knowledge of types that <xref:System.Memory%601> is able to represent. For example, you can derive from `MemoryManager<T>` to allow <xref:System.Memory%601> to be backed by a <xref:System.Runtime.InteropServices.SafeHandle>.
> [!NOTE]
> The `MemoryManager<T>` class is intended for advanced scenarios. Most developers do not need to use it.

</Docs>Before porting the docs into triple slash comments, this was the content of MemoryManager.cs:
/// <summary>
/// Manager of <see cref="System.Memory{T}"/> that provides the implementation.
/// </summary>
public abstract class MemoryManager<T> : IMemoryOwner<T>, IPinnableAfter porting, this is the result:
/// <summary>An abstract base class that is used to replace the implementation of <see cref="System.Memory{T}" />.</summary>
/// <typeparam name="T">The type of items in the memory buffer managed by this memory manager.</typeparam>
/// <remarks>The `MemoryManager<T>` class is used to extend the knowledge of types that <see cref="System.Memory{T}" /> is able to represent.

public abstract class MemoryManager<T> : IMemoryOwner<T>, IPinnableThe <remarks> section has the content duplicated, once inside the <format> and once before it, which is an invalid structure.
