As I tried to build a Web App out of a 3D-Scene with Web AppBuilder for ArcGIS Online using the Launchpad Design with custom color I noticed that the Search (full-text-search) is not styled correctly:
It has edges (first picture) instead of having rounded edges (second picture). This looks awful.
Usually when I build Apps from 2D-WebMaps I use the WAB with Launchpad Design and a custom color. When I do this the style of the full-text-search Widget changes to rounded edges.
But not if I do the same out of a 3D Scene.
I suppose this is a simple mistake in programming. Please fix it.
