Instead of using the layer borders, we use the bounding box for the contents. This is similar to first run "Crop to Content" on every selected layer except we don't actually need to crop. Therefore we can work on bigger layer than the actual content while still arranging them based on content bounds. So often the result of alignment/distribution feels wrong because it doesn't correspond to the content we are seeing. With this option, we'll have the option to choose the desired behavior.
