Steps to reproduce:
- Install `website_hr_recruiment` module
- Go to `your_website.com/jobs`
- Activate Edit mode and add a "3 Columns" block
- Select one of the columns and set the shadow to `None`
Issue:
Shadow is not removed, and by default the "outset" mode is selected.
Cause:
When we check the state of the shadow with `css('box-shadow')`, it
will always be set because a custom css 'box-shadow' is set by the
module website_hr_recruitment on card element, and therefore the value
will always be either 'inset' or 'outset'.
Solution:
If widget value is set to '', replace `box-shadow` style to 'none'
(only if needed) so it will override the style from css file.
