Flip Clock Widget: Shadow appears behind Clock Widget when using RGBA color

[ifarzana]

When applying an RGBA flip card background color to the clock widget, an unintended shadow appears behind the widget. This issue is not present when using an RGB background color.

Steps to Reproduce:

• Add a Flip clock widget to the layout.
• Set the Flip Card Background Colour of the widget using an RGBA value (e.g., background-color: rgba(0,0,0,0.7)).
• Observe the shadow behind the widget.
• Change the background to an RGB value (e.g., background-color: rgb(255, 255, 255);).
• Observe that the shadow issue no longer occurs.
