Viewport Renders black when accessing Toolbar dropdown in Mobile Render Preview

Viewport is rendering black when Preview Rendering Level is set to Mobile/HTML5 setting and the user hovers over settings options

This is a regression from 4.16.2

1. Open any project
2. Change Preview Rendering Level to any Mobile setting
   • in the Toolbar click Settings > Preview Rendering Level > Mobile/HTML5 > Default Mobile/HTML5 Preview
3. Go back into settings and hover the mouse in between options

Result: The viewport renders black, collisions/billboards still appear

Expected Results: The viewport renders normally
