[bug report] Nested masked-nodes cause "child-mask's" contents to disappear!

As described in title, this might be a bug of Cocos Creator. If I disable mask-component of the childNode then thing works fine.
Please test @pandamicro !

Can you post some screenshots ? I can’t be sure what you are talking about

Pls refer to below bug description

Sorry, I can’t reproduce the original bug but the case is a bit changed. I have the object structure like below

If both xMASK1 & xMASK2 have active mask component then “content2” disappears but content1 get shown. If I disable mask-component of either xMASK2 or xMASK1 then both content1 & 2 are shown.
