Empty output when FPP used inside minipanels

I have found a bug which will show empty regions. To reproduce that you have to follow these steps

1. Create Fieldable panel pane (fpp) type
2. Overwrite the output by entity_panels with a style you want
3. Create a mini panel
4. Add entites of the newly created fpp type
5. Create panel page which contain the created mini panel
6. Go to the panel page url
7. Nothing shows up from the mini panel contents
8. Clear caches and notice the contents are there
9. Reload the page and see the empty regions again

Here is the html output inside the minipanel looks like this

<div class="3-columns-33-33-33 panel-display panel-display--3-columns-33-33-33">
	<div class="region l-left">
		<div class="panel-pane pane-fieldable-panels-pane pane-uuid-3e2066ee-08fe-40d1-ac17-97ce8a09aa18 pane-bundle-feature">
			<div class="fieldable-panels-pane">
			</div>
		</div>
	</div>
</div>

Inside div.fieldable-panels-pane the content of the fpp should show up
