Custom components don't display previews

[AdrianSanduleasa]

Describe the bug
Custom components don't have a preview on 2.4.5-p1.

To Reproduce
Steps to reproduce the behavior:

1. Create a custom component
2. Go to Admin -> Content -> Blocks
3. Click on Add New Block
4. Scroll down to the content area and edit using Page Builder. Add a new row and inside that row, drag the newly created component which by default is "My Custom Type".
5. You will notice that there is no preview content. The following content is not present in the preview:
   <div class="my-class" attr="data.my_element.attributes" data-bind="liveEdit: { field: 'my_field', placeholder: $t('Your custom content type!') }"></div>

Expected behavior
Preview for custom components should be displayed.

It seems that the issue is coming from app/code/VendorName/MyCustomType/view/adminhtml/web/template/content-type/vendorname-mycustomtype/default/preview.html:2 from the selfclosing tag.
So in order to fix the preview, this:
<render args="getOptions().template"/>
Becomes this:
<render args="getOptions().template"></render>

This seems like an easy enough fix and it looks familiar. Was there a PR already merged that fixed this?
