Description

This is a tricky one to find. A featured image block with a set height will show correctly in the editor but the frontend will display something different. There's a couple of reasons to this:

• the img tag is not getting the height applied to the featured image block wrapper
• the editor has a different markup than the frontend (the anchor link when the featured image is a link is missing in the editor but present in the frontend)

Step-by-step reproduction instructions

On empty theme, paste this code on a page:

<!-- wp:query {"queryId":33,"query":{"perPage":3,"pages":0,"offset":0,"postType":"post","order":"desc","orderBy":"date","author":"","search":"","exclude":[],"sticky":"","inherit":false}} -->
<div class="wp-block-query"><!-- wp:post-template -->
<!-- wp:columns {"backgroundColor":"cyan-bluish-gray"} -->
<div class="wp-block-columns has-cyan-bluish-gray-background-color has-background"><!-- wp:column {"width":"50%"} -->
<div class="wp-block-column" style="flex-basis:50%"><!-- wp:post-title {"isLink":true,"fontSize":"x-large"} /-->

<!-- wp:post-excerpt {"fontSize":"large"} /--></div>
<!-- /wp:column -->

<!-- wp:column {"width":"50%"} -->
<div class="wp-block-column" style="flex-basis:50%"><!-- wp:post-featured-image {"isLink":true,"height":"100%","align":"wide"} /--></div>
<!-- /wp:column --></div>
<!-- /wp:columns -->
<!-- /wp:post-template --></div>
<!-- /wp:query -->

Ensure that there's an image on the post you are displaying and the text forces the image to stretch.

Check the frontend, the image is not stretching there.
