[xmonad] bug using NoBorders and HintedTile

[TeXitoi]

Because having a google account is against my religion, I post here a
bug report. Sumbit it to the bug tracker if you want.

The xmonad.hs showing the bug with comments:

########
import XMonad hiding (Tall)
import XMonad.Layout.NoBorders
import XMonad.Layout.HintedTile
import XMonad.Hooks.ManageDocks

-- open 2 terminals. focus on one. launch top inside. change layout twice

-- focused window do not follow hints
buggy = defaultConfig {
        manageHook = manageHook defaultConfig <+> manageDocks,
        layoutHook = avoidStruts . smartBorders $ tiled ||| Full
}

-- focused window will first not follow hints, and then follow.
flashing = defaultConfig {
        layoutHook = smartBorders $ tiled ||| Full
}

-- normal behavior, distributing smartBorders
workarround = defaultConfig {
        manageHook = manageHook defaultConfig <+> manageDocks,
        layoutHook = avoidStruts $ smartBorders tiled ||| smartBorders Full
}

main = xmonad buggy

tiled = HintedTile 1 0.03 0.5 TopLeft Tall
########

I didn't find the explaination, but I suspect smartBorder saying to
the layout that the focused window do not have border (because of the
previous layout without border) and that HintedTile compute the size
of the window as there is no border, and then smartBorders add the
borders (resulting of a smaller window that do not follows hints).
