Space Vertical & Space Horizontal Spacing field isn't keyboard focusable (Sketch 53)
Since Sketch v53, when I run the `Space Vertical` or `Space Horizontal` commands, the `Spacing` input field isn't focused by default, and won't get focus if I try and shift tab back to it. Keyboard focus cycles only between the `Cancel` and `OK` buttons.

The field can of course still be clicked and then edited. But that slows me down considerably.

I never realize how much I rely on plugins until the team updates Sketch and breaks a command or two. 😭
