Properties in computed callback are missing when reset to default value

[xxtesaxx]

In the callback of a computed property, the computed_depends_on properties are not passed correctly after resetting them.

For example, I have a computed property "__something" which has the computed_depends_on field "a". a has the default value of 5.

When the module is loaded for the first time, 5 is correctly passed to the callback function in the $args array (first argument of the function).

When I change a to 1, then 1 is correctly passed.

When I then remove the value of a, the builder displays 5 (greyed out), the field is basically empty. a in the callback function is now not 5 but empty as well.

When I change a back to something different, the reset button appears. Resetting it (at least on text fields) will now actually write 5 into the field. I can also write 5 in the field myself and the reset button disappears again. Now 5 is passed to the callback.

Some other fields behave strange as well like dropdowns and buttons. I think is this is a general problem and will apply to all field types.
