@Cntlsn -- is this something we should fix?

That's a focus outline and is an accessibility helper for keyboard users and an upstream issue of OOUI. The only workaround is not ready yet for production due to missing browser support T172578. My recommendation: decline.

@Volker_E Thanks for clarifying. This question comes up all the time.

Thanks @Volker_E for the clarification.

@MMiller_WMF about the icon's vertical alignment issue, it only happens (in both mobile and desktop) for rows with a real image because there is an issue with the image container's class.
To me the following fixes it (on both desktop and mobile):

.growthexperiments-homepage-module-impact .impact-row .article-image .real-image {
    background-position: center;
    display: inline-block;
    vertical-align: middle;
}

But I would leave it to @SBisson @kostajh to decide what's the best way to approach it.

Thanks @Volker_E. I modified the issue description to only be about the vertical alignment of the icon.

This is ready for development.

Checked in betalabs - the alignment seems to be in place:

The Impact module on the Homepage shows 0 for the number of views that haven't been calculated yet. Is it intentional?

@Etonkovidova that will be addressed in T225560: Homepage: mobile preview when calculating

Looks good to me, moving to "Needs PM Review"

I'll resolve this once this looks good in production with next week's train.
