background-blend-mode is no longer functioning as it should with color option

Hi,

I created a website with a pretty simple css in the body of the page. I have a background image, but its colors are too dominant, so I also added a background color property to make the background more "pale". This approach worked perfectly in Chrome and I am 99% sure that I also tested this back then in Firefox and it worked as expected.

Now, only a white background is displayed in Firefox (Chrome works perfectly), which is interesting, because nor the image nor the set colour is white (well... the colour is white, but it is semi transparent). Did I miss something or is this an accidentally added bug in Firefox?

For your reference I attach a minimal working (in Chrome the paler background is displayed properly, in Firefox white page) example (note: change image url to whatever):

html: 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <script src="script.js"></script>
</body>
</html>

css:
body{
    height: 100vh;
    width: 100vw;
    justify-content: center;
    align-items: center;
    display: flex;
    margin: 0;
    flex-direction: column;
    background-image: url(./resources/splash.jpg);
    background-position: center;
    background-size: cover;
    background-color:  rgba(255,255,255,0.1);
    background-blend-mode:color;
}

I appreciate the help, Mark

It works for me. Blending can be affect by graphics driver bugs, does it still happen in Troubleshoot Mode?
