Badge small icons vertically on iPhone

Small icons for Google, Facebook etc. on the badge are displayed vertically on my iPhone 12 Mini. I'm using badge style 2. On different browsers' inspect tool with mobile device view enabled the small icons are in line horizontally, and with responsive view I can shrink the view to be super narrow and still the icons remain horizontal, but on iPhone even having the phone in landscape mode shows the icons vertically. I couldn't find any CSS to fix this by myself.
