Widget node depends with block parameter

[gabs77]

On Magento 2.1.2, When we create specific widget, the node "depends" has some difficulties to turn well.

    <parameter name="url_type" xsi:type="select" visible="true" required="true">
            <label translate="true">Type Link Bloc</label>
            <options>
                <option name="product" value="product" selected="true">
                    <label translate="true">Product</label>
                </option>
                <option name="custom" value="custom">
                    <label translate="true">Custom</label>
                </option>
            </options>
        </parameter>
        <parameter name="id_path_product" xsi:type="block" visible="true">
            <label translate="true">Product</label>
            <depends>
                <parameter name="url_type" value="product"/>
            </depends>
            <block class="Magento\Catalog\Block\Adminhtml\Product\Widget\Chooser">
                <data>
                    <item name="button" xsi:type="array">
                        <item name="open" xsi:type="string" translate="true">Select Product...</item>
                    </item>
                </data>
            </block>
        </parameter>
        <parameter name="custom_url" xsi:type="text" visible="true">
            <label translate="true">Link Bloc</label>
            <depends>
                <parameter name="url_type" value="custom"/>
            </depends>
        </parameter>

Expected result

When the user select the type parameter as product, the custom link parameter has hidden and the product link has show.
When the user select the type parameter as custom, the product link parameter has show and the product link has hide.

Actual result

When the user select the type parameter as product, the custom link parameter has hidden. It's perfect.
When the user select the type parameter as custom, the product link parameter has always shown.

It seems to me that this is a duplicate of #6868 and faces exact the same problem. Although I think, the problem is described a bit better here.

It's not perfect but it's hide a button chooser block
