New opened documents don't have focus

When I click on a document file to open it, it will open but only in the background, so I have to click on it again to get focus so I can read it.

Why does Libre Office do this, it is so annoying. This bug has been around for years, I see references to this going back to 2012. It even has a bug number 339 621.

Please, can someone help me?

I’m using 4472 on Windows 10
