Dummy div in a IWRegion

[StephB]

I don't think that the root cause of the problem was solved (no info here), but I don't download the last release, and now I'm no longer working on this project.
As a workaround, I set a double CSS class to manage the expected region with or without a dummy DIV.

Code:

[id^="IWREGIONRELATIONS"] div, [id^="IWREGIONRELATIONS"] {
    display: flex;
    flex-direction: column;
    padding: 5px;
}

Not a perfect solution, but the render is correct in both case.
