Widget parameter depends does not work on specified block

[LordHansolo]

Preconditions

1. Magento 2.1.1

Steps to reproduce

1. Create Module adding Custom Widget
2. Add Parameter like <parameter name="catalog_url" xsi:type="block" visible="true" required="true" sort_order="33"> <label translate="true">Category</label> <depends> <parameter name="enable_url" value="1" /> <parameter name="target_url" value="1" /> </depends> <block class="Magento\Catalog\Block\Adminhtml\Category\Widget\Chooser"> <data> <item name="button" xsi:type="array"> <item name="open" xsi:type="string" translate="true">Select Category...</item> </item> </data> </block> </parameter>
   
   It is important to use block class="Magento\Catalog\Block\Adminhtml\Category\Widget\Chooser" or block class="Magento\Catalog\Block\Adminhtml\Product\Widget\Chooser".
3. Set any custom depends.
4. Go to admin panel. Add your widget. In widget options change parameter that our parameter depends on.

Expected result

Our Parameter disappears, if conditions set on depends are not met.

Actual result

Parameter is visible anyway.

It's also an issue in Magento 2.1.2. And, in my opinion, it is not important which block class you use, as this is a general issue with all parameters of xsi:type="block" depending on another parameter.

In #5443, you find detailed info of the expected/actual for the problem (display:none; is set on the wrong html element). I can confirm that these are the same for this one!
Maybe, this is a duplicate of #5443 (but the steps to reproduce are a bit different).
