AdminDateWidget calendar prev next links are invisible in 3.0.8

[AndrewYatskevich]

Hello colleagues

We are using django-grappelli in our project. After updating to 3.0.8 the arrows of AdminDateWidget calendar got invisible. They don't show up in Google Chrome browser.

I've created repo to reproduce this bug. Please, check it out: https://github.com/AndrewYatskevich/bug-repro-invisible-arrows

OS Ubuntu 22.04.4 LTS
Browser Google Chrome Version 124.0.6367.118 (Official Build) (64-bit)

Best regards,
Andrew

@AndrewYatskevich I can't reproduce this quickly with my local setup, but have you checked whether the static files are loaded? The icon is part of a sprite map and should actually be visible if it can be loaded.

@AndrewYatskevich Sorry, can reproduce it with Chrome (used Firefox before). I will take a look at that.

@AndrewYatskevich fixed in stable/3.0.x, see commit above.

I couldn't find the exact reason but Chrome seems to have a problem rendering background-image: url(my_transparent_icon.png) with background-color: transparent defined separately. Using the shorthand background: url(my_transparent_icon.png) x y, repeat, color) avoids the problem.
