Comment:

 == Test Report

 === Steps to Reproduce
 1. SETUP: Apply setup patch from comment:12. This is required to apply the
 `safecss_filter_attr()` fix from 6.0.3.
 2. Create a new post.
 3. Insert a Post Featured Image block, add an image to the block (should
 be taller than 100px).
 4. Set the height to 100px and scale to "Cover".
 5. Publish post and view the new post.
 6. 🐞 Observe that the image in the block is stretched in the frontend
 (and preview).

 === Expected Results
 - ✅ Block's image in frontend is set to 100x100px, instead of "object-
 fit: cover". (See Figure 1.)

 Patch tested: attachment:56855.1.diff 👍🏻

 === Environment
 - Hardware: MacBook Pro Apple M1 Pro
 - OS: macOS 12.6

 - Server: nginx/1.23.1
 - PHP: 7.4.32
 - WordPress: 6.2-alpha-54642-src

 === Actual Results

 "object-fit: cover". (See Figure 2.)
