In XML documentation, some XML entities disappear

[hhmmjjnn]

Code:

internal class C
{
    /// <summary>
    /// Foo&lt;br&gt;bar.
    /// </summary>
    /// <remarks>
    /// Spam<c>&lt;br&gt;</c>baz.
    /// </remarks>

    public const int foo = 42;
}

VS:

VSCodium:

The expected behaviour (VS) is that < is rendered as < and &gt as >.

The observed behaviour (VSCodium) is that < and &gt disappear, as well as everything between them.

May or may not be related to another report:

• In XML documentation, URL tag damaged when followed by a period #2654

Nota bene:

internal class C
{
    /// <summary>
    /// These work:
    /// <list type="bullet">
    /// <item><description>Unbalanced: foo&gt;bar</description></item>
    /// <item><description>Unbalanced: foo&lt;bar</description></item>
    /// <item><description>Other entities: foo&amp;bar</description></item>
    /// </list>
    /// </summary>
    /// <remarks>
    /// This, doesn't:
    /// <list type="bullet">
    /// <item><description>Partially &lt;&lt;foo&gt; balanced.</description></item>
    /// </list>
    /// </remarks>
    public const int foo = 42;
}
