[Bug] Enum Member "remarks" Elements Not Displayed

[xLEGiON]

Describe the bug
The "remarks" elements for enum members are not displayed in the documentation when using the default "mref" output format.

To Reproduce

public enum Test
{
    /// <summary>
    /// Summary text for first.
    /// </summary>
    /// <remarks>
    /// More details about first here.
    /// </remarks>
    First,

    /// <summary>
    /// Summary text for second.
    /// </summary>
    /// <remarks>
    /// More details about second here.
    /// </remarks>
    Second,

    /// <summary>
    /// Summary text for third.
    /// </summary>
    /// <remarks>
    /// More details about third here.
    /// </remarks>
    Third
}

Expected behavior
They appear correctly when using the "apiPage" output format, but should also appear for the default "mref" output format.
