Custom css theme loads but gets overwritten by default theme, possibly issue with z-index?

[mlubej]

I have a custom css file which loads an image and adds it in the top right corner. I add the custom css using the front matter:

---
theme : "blood"
customTheme : "custom"
___

custom.css content:

body {
    background-image: url(figs/logo.png);
    background-size: 10%;
    background-repeat: no-repeat;
    background-position: 95% 5%;
}

When I refresh I see the image from the custom css file loaded, but then quickly overwritten with the theme background, which made me think there is an issue with the z-index or something.

• Tried this with versions 4.3.3 back to 4.1.0, same issue
• It works for 4.0.3, but this one has other issues, like html comment background settings not working
