Comment 10 for bug 1804621

Hi Jérôme, I reverted 7c60d78 and friend for you since I did not see reaction yet. We can't keep unsure code in daily builds, sorry.
Feel free to fix and recommit when everything is sorted out (if it is really worth it, I'm really not sure since the side effects are very intricate).
Bruno
