Label with a filter (such as a DropShadowFilter) won't show up when in a SkinnablePopUpContainer

Steps to reproduce:
1. Use a Label with a filter within a SkinnablePopUpContainer:
<s:Label width="100%" text="Text with filter NOK" filters="

" color="0xFFFFFF"/>
2. Open the SkinnablePopUpContainer
3.

Actual Results:
Text is not shown unless there is a display list invalidation

Expected Results:
Text should be shown with the effect

Workaround (if any):
Don't use SkinnablePopUpContainer (works fine with Group) or don't use filters

Please find a attached a project to reproduce the bug. Notice that the 2 first Labels in the View are shown correctly. Press the "open" button and the pop-up should show 3 texts but only the first one (no filters) is shown. Note that if you touch the validate button, the text appears, surely because of a display list invalidation or something.

This bug can be reproduced on Android and iOS on device but not in the emulator.
