[BUG] Incorrect border radius controls

Changing border-bottom-left-radius prop changes bottom right radius, and vise versa. Reproducing:

1. Go to https://jsfiddle.net/szLp8h4n
2. Add, for instance, any image
3. Try to change border-bottom-left-radius prop in Decorations section

Playing around config didn't help much, the best one fixes naming problem but reorder controls themselves. So, the config like:

{
    property: 'border-radius',
    type: 'composite',
    properties: [
        {
            name: 'Border Top Left Radius',
            property: 'border-top-left-radius',
            type: 'integer',
            defaults: '0px',
            min: 0,
            units: ['px', '%'],
        },
        {
            name: 'Border Top Right Radius',
            property: 'border-top-right-radius',
            type: 'integer',
            defaults: '0px',
            min: 0,
            units: ['px', '%'],
        },
        {
            name: 'Border Bottom Left Radius',
            property: 'border-bottom-right-radius',
            type: 'integer',
            defaults: '0px',
            min: 0,
            units: ['px', '%'],
        },
        {
            name: 'Border Bottom Right Radius',
            property: 'border-bottom-left-radius',
            type: 'integer',
            defaults: '0px',
            min: 0,
            units: ['px', '%'],
        },
    ],
},

...results in: (notice bottom radius controls reorder)
