Hi Team,

While randomly going through websites, I came across following bug:

*** Steps to Reproduce ***

1. Go to https://www.mercedes-benz.com/en/
2. Click on Vehicles and see first column of options
3. Notice `arrow` next to Mercedes-AMG

*** Expected Result ***

It should be on same baseline.

**** Actual Result ***

It is not on same baseline.

*** Other Browsers ***

WebKit ToT (312470@main) [Minibrowser] - Broken
Chrome Canary 149.0.7820.1 (Official Build) canary-dcheck (arm64)  - Works fine.
Firefox Nightly 152 (20260430212929) - Works fine.

Thanks!
