`inheritdoc` entries are not followed and resolved in our tooltips/documentation

Details

The StreamJsonRpc.JsonRpcTargetOptions.UseSingleObjectParameterDeserialization property (and several others on this type) make use of <inheritdoc cref="some_other_member"> to reuse xmldoc. This looks like this in the generated xmldoc:

<member name="P:StreamJsonRpc.JsonRpcTargetOptions.UseSingleObjectParameterDeserialization">
  <inheritdoc cref="P:StreamJsonRpc.JsonRpcMethodAttribute.UseSingleObjectParameterDeserialization" />
  <remarks>
      This value serves as a default for <see cref="P:StreamJsonRpc.JsonRpcMethodAttribute.UseSingleObjectParameterDeserialization"/> for members that have no <see cref="T:StreamJsonRpc.JsonRpcMethodAttribute"/> applied.
  </remarks>
</member>

In Ionide, we don't render this in the tooltips and info panel:

We need to be able to follow the cref inside this element and merge the docs from one member into another.
