Dashboard: Logs widget has only several rows - short scrollbar

Only latest several rows are displayed in Logs widget. No header displayed.
I would expect same amount of logs in the widget as it is at the Logs page, scrollable according to widget's size.

But if I select only ERROR logs, there is only one ERROR log in the widget. With table header.
I would expect it to behave the same way as in preceding case.
