I already check many answers regarding the move `header.links` to `header-wrapper` its working but the problem is that it also move my custom links to header content.

I am trying to create a new container which has a parent `header.links`, but 
its not working.

here is my default.xml

        <referenceContainer name="header.links">
            <container name="custom-content" as="custom-content" label="Page Custom Content" htmlTag="div" htmlClass="custom-content">
            </container>
        </referenceContainer>

        <move element="custom-content" destination="header-wrapper" />

        <referenceContainer name="custom-content">
            <!-- Contact us Link -->
            <block class="Magento\Framework\View\Element\Html\Link" name="contactus.link" after="register-link">
                <arguments>
                    <argument name="label" xsi:type="string" translate="false">Contact Us</argument>
                    <argument name="path" xsi:type="string" translate="false">contact-us</argument>
                </arguments>
            </block>
            <!-- CMS Page Link Link -->
            <block class="Magento\Framework\View\Element\Html\Link" name="aboutus.link" after="contactus.link">
                <arguments>
                    <argument name="label" xsi:type="string" translate="false">About Us</argument>
                    <argument name="path" xsi:type="string" translate="false">about-us</argument>
                </arguments>
            </block>

            <!-- CMS Page Link Link -->
            <block class="Magento\Framework\View\Element\Html\Link" name="customerservice.link" after="customerservice.link">
                <arguments>
                    <argument name="label" xsi:type="string" translate="false">Customer Service</argument>
                    <argument name="path" xsi:type="string" translate="false">customer-service</argument>
                </arguments>
            </block>
        </referenceContainer>

First I create new container `custom-content` then I move existing links like `Sign in`, `Create an account` link & `Greeting message` to `header-wrapper` and then define my custom link into my custom container, but its not working.

if I remove custom container then move is working fine.
