How to reproduce the issue:
Add this to your config:

clientbuttons = awful.util.table.join(
    awful.button({ modkey }, 1, awful.mouse.client.move)
)

Actual result:

The bind only works after you press any other key combination which involves the modkey and hold the mouse button without releasing the mod key

Expected result:

Windows can be dragged with a mouse even after releasing the mod key and pressing it again

I can't find it right now, but I am pretty sure this is a duplicate. There's some corner case when the layout changes what are not handled well. Beside moving to libinput directly, I am not quite sure how to fix this.
