When I try to add a CSS Size field in a content type, it shows an error.

1: Install the "Css size field" using the following command:
composer require 'drupal/css_size_field:^1.0@beta'

2: Add a CSS Sixe field to any content type.

3: The following error appears:

InvalidArgumentException: Invalid weight unit "" provided. in Drupal\css_size_field\SizeUnit::assertExists() (line 62 of modules\contrib\css_size_field\src\SizeUnit.php).

The issue was caused because there was no validation to check $default_value['unit'] for being empty in /src/Element/CssSize.php. Changes have resolved the issue. Moving it to NR.
