ArrayIndexOutOfBoundsException in updateLayoutState()

See original GitHub issue

Hi, I have a crash from time to time when updating data. It looks like updateLayoutState() throws an IndexOutOfBoundsException here:

FlexboxLayoutManager line 2057

int firstVisiblePosition = getPosition(firstVisible);
int firstVisibleLinePosition = mFlexboxHelper.mIndexToFlexLine[firstVisiblePosition];

getPosition(firstVisible) seems to return -1 (NO_POSITION) sometimes. Maybe this is related to the activity being hidden behind another. It happens at least on versions 0.3.0 and 0.3.1

Here is the full stacktrace:
