How to require urlInput on custom component ui_component form?

[jmgardner]

I'm trying to make the urlInput a required field in the ui_component form in a custom component. I'm able to make other fields required using the below validation method, but it won't work for urlInput.

The user is able to save the form even with a blank text field. That, coupled with the asterisk being next to the URL field (see image below) leads me to believe that the "required-entry" is applying to the the link type drop down and not the text field where the user would enter a URL or select a site link.

Does anyone know how I could make the URL field a required one within the custom component form?

Code:

...
<urlInput name="link_url" sortOrder="30" template="Magento_PageBuilder/form/element/url-input">
    <settings>
        <dataType>text</dataType>
        <label translate="true">Link</label>
        <dataScope>link_url</dataScope>
        <urlTypes class="Magento\Ui\Model\UrlInput\LinksConfigProvider"/>
        <validation>
            <rule name="required-entry" xsi:type="boolean">true</rule>
        </validation>
    </settings>
</urlInput>
...

With that code in the ui_component.xml, it shows up like this:
