Pressure acts in 3 dimensions. If the Ice is anchored to the glass, then the forces are transmitted. A hole in the ice with liquid water under it is OK for the water, the ice, however, is still exerting force against the glass. Now if you cut the ice away from the glass so that it was truly floating in the water, then there is only the effect of mass.

My response about gravity presumed that A.) the ice was not floating, and B.) there was no hole in the ice to allow further expansion of the water.
Some people need to reimagine their thinking.
