Python-defined property does not start with default value

Question

I am defining an extra property for all objects like this:

bpy.types.Object.alpha = bpy.props.FloatProperty(
    default=100.0,
    min=0.0,
    max=100.0
)

However, when adding new objects, they start with their alpha at 0.0:

Making matters even more confusing, right-clicking the property and selecting 'reset to default' correctly sets the value to 100.0:

How can I ensure that new objects correctly start with this default value?

If you have a getter / setter set up on property with issue post code in question. As it stands now the question / answer do not correlate. The default value of simple property defined via code above will be correct.

Turns out it was a problem with the getter I defined:

def get_alpha(self):
    return self["alpha"] * 100.0

should be

def get_alpha(self):
    if "alpha" not in self:
        return 100.0
    return self["alpha"] * 100.0
