Inner Grid Looks different depending on Web Browser

My inner grid looks different depending on the Web Browser

This one looks correct (Internet Explorer)


the color of the third level grid is incorrect (Chrome)


I tried changing the color to black, thinking it was a problem with hex, and the result was the same.

I tried to create a ticket for this but it said my license had expired (which is not true).

The problem was solved in the support.
Please, try to use the “background” attribute insterad of “background-color” in your setStyle() method.
