[annexation] Loosing my selection

[jcfrog]

When playing a Annexation game, my turn, all white selected, if I resize the window, the board is redrawn but the selection has disappeared, nothing you can do except "step back" to restart properly the display.

I also noticed a selection lost in Tafl games but not the same way and can't reproduce it clearly.

This happens on Linux/Firefox too
