How to reproduce the issue:

Try to resize a floating client with the mouse (Mod4 + Right click + drag)

Actual result:

The mouse snaps to the top left corner of the client every time and starts resizing the client from there, even when the mouse snaps to the expected corner (the closest one to the mouse) right before the user starts moving the mouse to resize the client.

This is reproduced using the default configuration.

    awful.button({ "Mod4" }, 3, function (c)
        c:emit_signal("request::activate", "mouse_click", {raise = true})
        awful.mouse.client.resize(c)
    end),

Expected result:

The mouse should not jump and instead stay snapped to the expected corner, and resize the client that way.
