I think you need to caveat this only slightly.

1) At the moment when the sea ice breaks off there is no rising in overall level due to fact that the ice displaces the same volume of water as is in it.

2) during the melting phase if the sea water around the ice is greater than 4 degrees, the melting will cause a temporary drop in the local temperature of water causing the water level to in fact drop slightly.

3) in the LONG term, the additional volume of liquid water added by the ice will be warmed and expand causing a slight increase in water level due to thermal expansion (assisted by the change in albedo of the whole system as you mentioned)
