How to properly set default values?

[Chantal]

I have set an attribute with a default value:

attributes: {
width: {
	type: 'number',
	value: 425
},
height: {
	type: 'number',
	value: 450
},
},

In the edit function I use:

<TextControl
	label="Size"
	value={ width }
	onChange={ ( width ) => setAttributes( { width } ) }
	className="width"
/>

Now when I add my block in the editor, the default values are shown, but not saved to the post/page. Unless I edit them to another value and then save my post/page. What am I missing?

Yup, I have noticed the same thing.

Default attributes do not save as attributes unless changed or you call set attributed a first time to manually save the value.

It seems like a bug, but I think they did that on purpose.
