How to prevent thicker outline on dropdown menus when clicked?

[jaesielee]

hello,

Whenever I click sizes or colours, it outlines thicker, see the photos.

I don’t want any changes when you click dropdown menus.

I just want the thin outline as is when clicked.

I dont want the thicker outlined box.
