Adding a custom class prevents the bar showing red in error mode

[cjmyles]

I added a custom class to the HTML:

<loading-bar
    custom-class="custom-class"
    ...

Then set the error mode in the JS:

this.error = true;

The loading bar appears, but in green not red. Without the custom class there is no issue.

Hi @cjmyles, how about custom css?

.CustomClass.LoadingBar--error {
   background: red;
}
