Inconsistent search-box style in the AppGrid
In Gnome 3.34, the AppGrid has now a search-box with round edges (macOS style). However, everywhere else in the theme, the search-boxes have squared edges.
Expected behaviour : the AppGrid search-box should have squared edges like all other search-boxes of the Adwaita theme.
(1) other than the fact that there’s no apparent reason for the theme to use different styles for search-boxes ; (2) the search-box with squared edges gives a distinctive touch to the Adwaita theme and provides an original style when compared to other Operating Systems (i.e. MacOS) ; and (3) the theme would also look generally more consistent if all search-boxes would have squared edges.
