I have dual-monitor setup
When i use just modkey + 1/2/3/4 when i focused on client on second screen, it changes workspace on that screen, which is fine and how it should work.

But when i press buttons (left panel) and i didn't click on anything on left screen, it moves first client from right screen to left screen to workspace that i clicked.

I tried searching through awesome/widgets/tag-list.lua, but couldn't find behaviour that would describe such issue.
