_getGridHeight() returns truncated height due to rounding down

Edit: previous issue was fixed

I think you mean to round the pixel value at the end, otherwise you'll end up with a missing row when Math.floor rounds down. I'd suggest this instead:

Math.floor((this.props.entries.length / this.state.itemDimensions.itemsPerRow) * this.state.itemDimensions.height);
