Fix repeated backgrounds for cover srcset

[ajlende]

Description

Repeated backgrounds aren't working. That feature #26001 came along after this PR was made but got merged before it (#25171). I remember seeing it discussed #25421 (comment) that setting the Cover to have a fixed background is an exception to the img/srcset being used. So it would seem the repeated background option should trigger that same exception.

See #25171 (comment). Thanks @stokesman for reporting the bug.

This just adds a check for isRepeated in addition to hasParallax for using background styles.

How has this been tested?

• Use the repeated background in the cover block. See that it still works.

• Checkout cfe936a (commit before Add srcset for cover image #25171). Add the old block to a post and save the post. Checkout this branch. Re-open the post. See that the deprecated block gets upgraded.

I copied this from the save function prior to the srcset change. The useBlockProps must have been added in addition to the isRepeated before the srcset change was merged.

The code looks good and in testing I didn't find any issues.

So I'm just a little late to the party. I'd just captured a screen recording to post here when I saw it'd been merged. I would have recorded/posted earlier as I had tested this yesterday but I assumed what I saw was going to be caught by others.

Maybe I'm the only one seeing this but in my testing, this didn't appear ready. The repeated background is showing but also layered with the same image in the img element. The image I'm testing has transparency or else the repeated background would be obscured. Also, I forgot to capture it in the screen recording but the focal point picker only responds on vertical axis.

It'd be great if there's just something going on with my setup and this is not reproducible.

@stokesman I must not have noticed because I had a large image without any transparency. I added a fix in #28362
