When using a RGBA string, the alpha is lost

[304NotModified]

When setting the value "rgba(0, 128, 0, 0.57)" (so a string)

The value is parsed correctly to the tinyColor (inside _colorChange(data, oldHue))

but because data is still a string, var alpha = data && data.a; will be undefined and _colorChange is setting color.setAlpha(alpha || 1); :

expected behavior:

when setting "rgba(0, 128, 0, 0.57)" (string), it should work

current behavior:

it will be parsed correctly, but the alpha will be overwritten to 1 - we lose the alpha component
