'Version Control' tool panel not selectable after tab switching

I found that the 'Version Control' panel(called out by 'command + 9' on my Macbook) seems to losing focus after switching the tab(e.g., 'Local Changes' to 'Log', or 'Log' to 'Local Changes') and I won't be able to navigate through the commit history(by Mac built-in command + p/n navigation shortcuts or simply by the up/down key), nor navigate through local changes(by up/down key) purely using shortcuts. But without switching the tab, the shortcuts works fine. 

I remember that previous versions of WebStorm doesn't have trouble on this scenario. Please have a look, thanks.

One more feature request: can we support navigating through the 'Local Changes' with Mac's built-in supported navigation shortcuts(cmd + f to forward equivalent to ->, cmd + b to backward equivalent to <-, cmd + n to navigate down equivalent to down key, etc) like the 'Log' tab did? That would be convenient for HHKB users like me without moving my hands off the main area of the keyboard to press the fn + x to navigate down/up/left/right? Would love to hear your thoughts.
