Cant scroll up/down in log window

Having run my notebook (JupyterLab) I got an error in the Log-window. But the scroll isn’t working, it seems completely disabled or froozen. Cant click and drag nor use scrollwheel of my mouse. This actually happens sometimes even when no error is presented in the window. Haven’t found any bug-report or other threads meantioning this.

This sound like a bug. Would you mind reporting it on Issues · jupyterlab/jupyterlab · GitHub with reproduction instructions and version information?
