New Documentation icon does not display correctly
Open Pages dialog, the icon in the button for "New Documentation" is much smaller than the others. It's very difficult to see. This happens with multiple icon and Gtk themes. Even when an icon theme doesn't have the
devhelp-symbolic icon and displays an empty icon, it displays in the same small size. I assume this means that it's not an issue with the icon itself.
Also, with Adwaita icon theme, the icon displayed does not seem to be symbolic. With Adwaita-light Gtk theme, the light icon is invisible on the white background.
Expected behavior: the dimensions and style of the icon will match with the other icons in the dialog.
