[BUG]: Google pay button border looks thicker with white theme

[eponae]

What happened?

Hello, I would like to use the white google pay button thanks to the express checkout element on a white background container. Unfortunately, it looks like the top and bottom borders of the button are thicker with the white theme. I couldn't find how to overload this style as I would like the borders to be thin just like the left and right borders.
Anyone knows if it's possible? Thanks for your help

Here is a screenshot of the demo and a screenshot of how it looks with a different border radius.
