Advance BBCode Box on Milk theme

Problem

Some features of the Advance BBCode box extension (available separately) don't work in the Milk theme.

A z-index layering issue in Milk. The extension is working as intended, but hidden behind Milk's white background wrapper.

We are working on a permanent solution. Until then, you can remedy the problem by following these steps:

Open: /styles/milk_v2/theme/common.css

Find:

.darken {
    position: fixed;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    opacity: 0.5;
}

Remove

position: fixed;

Save changes, then purge cache.
