If no background color is set, the background color is transparent. But the whole site background color is white, so if you choose white or a color that is nearly white as font color the iframe appears so be empty.

This commit implements a new function that tests if a hex color is nearly white and if yes the code will change the background color to a grey color.

Fixes #14008
