The search button in the top bar was lost its style on the stackexchange.com -> Newsletters page. The search button style is fine on the other pages.

GIF for the same:

When an inspect the element, the following style was overridden in the .top-bar .searchbar .btn-topbar-primary CSS class, that caused the styling issue:

background-color: #0095ff;
padding: 0 12px;

The issue has been fixed recently.

The CSS class is fine now, so the search button for Newsletter is displaying correctly.
