details-control not visible

dascoco

I added child rows to my table and set the CSS for details-control like described

But the details-control isn't visible.
In Browser Dev-Tools I can see that CSS is applied correct to the element, the cursor also changes to pointer just the image isn't shown. When I set the CSS in Dev-Tools everything is shown correct.

Does anyone have an idea what could cause this problem? I also tried already to remove all other custom CSS.

Did you provide the CSS that is shown in the CSS tab of the example? Basically you need to point to the location of the PNG files.

Yes I use the CSS shown in the example, the location of PNG is correct.
As I mention if I add the CSS in Dev-Tools with the same path of PNG it's working.
That's why I don't understand it doesn't work.

Styling issues are difficult to troubleshoot without seeing them. Are you able to provide a link to your page or a test case replicating the issue?

If you inspect the details-control column do you see the background: url... is enabled or overridden?

If you look at the browser's network inspector tool do you see the PNG files loaded successfully?
