I wonder how do you , guys, declare the bug as invalid while the issue is exists and it's still relevant. You could at least call it duplicate with a reference to another issue, but INVALID it is not. To the point: This issue is relevant for me on a freshly installed Kubuntu 19.04. I tried to use the workaround proposed by @ronny, but it doesn't look as a good idea:
