Button Slicer Bug - custom border color

[tpavkova]

Hi, 
I encounter a bug in PBI Desktop in custom settings for the new 'Button Slicer' visual.
In Format visual - Buttons - Border it is impossible to change the color for any other than default gray. This issue affects the 'Hover' and 'Press' setting.
