Font color and background color buttons don't set the style at the current cursor position

Using Chrome/Firefox with font color and background color button added to Atto toolbar

Both buttons, when clicked, don't set the style at the current cursor position. For example:

• i'm typing "this text going to be red"
• select the color red in the fontcolor button
• continue typing "this should be red" but it still black.

You need to select the "this should be red" text and then select the color to actually change it. I thought there was a similar problem for bold and italic that was resolved since but I can't find the related issues in the tracker right now.

In the end, font color and background color button should behave like bold or italic.
