Kendo Inline Editor selected text background color

Hello,
I have a problem with setting the selection color in Kendo Editor in inline mode.
What I've discovered is that if a text inside the editor is not formatted everything is fine (meaning, selecting text with mouse highlight it with system defined color). Eveything breaks when add some styling. Bolding or underscoring text results in while color when selecting text.

I've observed the same issue on Components page (http://demos.telerik.com/kendo-ui/editor/inline-editing)

What could be the solution for this issue?
