Unfortunately I have to confim this incorrect behavior in Linux.
Yes, clicking the checkboxes does also switch/activates the plugin view
Although I have found that if you click the checkbox with
Shift modifier, then it does not switch the plugin, but I am not sure if it is reliable enough to use it like that. Anyway, the behavior is different from Windows (and Mac too, I think).
