Focus loss when switching between tags on multiple monitors

[Viacheslav Mikerov]

I am using two monitors and I wish to switch tags on both monitors, so I am
using this for the tag switching function:

                   for screen = 1, screen.count() do
                        local tag = awful.tag.gettags(screen)[i]
                        if tag then
                           awful.tag.viewonly(tag)
                        end
                    end

The problem is that all the time when I switch between tags, I lose window
focus if it was on the first screen.

How can I fix that?

Best Regards,
