Unify a logic for processing the bean property 'scope'

By default a bean is created without the property 'scope' such as

<bean class="aaa.HelloBean" id="helloBean"/>

but once we select the bean and open Properties view then the property is added as follows

<bean class="aaa.HelloBean" id="helloBean" scope="singleton"/>

Moreover, the editor is set as dirty and must be saved. This also happens if we import an existing project which contains a bean without any scope.

I suspect that it is caused by the combo box in Properties view which contains which automatically sets the default value. Is it possible to not add such property whenever we edit it via Properties view?

If not then please automatically add the property to all newly created beans.
