If a developer makes this error, it would prevent calls to key lifecycle methods, such as -layoutSpecThatFits:.
Although the superclasses of ASDisplayNode do not implement +initialize, a super call is added here for consistency.
Normally measure will be called before layout occurs. If this doesn't happen, nothing is going to call it at all. An experimenting developer probably added a node to the hierarchy directly. We simply call measureWithSizeRange: using a size range equal to whatever bounds were provided to that element. This make initial experimentation using layoutSpecs much easier. Furthermore added logging if no size is given for the node before layout occurs.
* make variable naming reflect ASEnvironmentTraitCollection vs ASTraitCollection
* move trait propagation to cell allocation instead of via a nested block
* move trait propagation when setting a displaynode's supernode instead of when adding a subnode
* fixed misspelling of "colection"
The crash happens in the placeholderImage of ASTextNode. The node is not visible in the time it try to get the `placeholderImage` and so the `visibleRange` has count 0 and a crash happens while accessing the first object of an empty array.
Summary: Don't set the new one in the subnodes yet as this will cause ASEnvironmentTraitCollectionIsEqualToASEnvironmentTraitCollection to return NO if only the displayContext changed.

- Add ability to measure the ASEditableTextNode based on the content now by calling measure:
- ASEditableTextNode considers preferredFrameSize now
- Fix crash if ASEditableTextNode is included in a horizontal stack
- Add tests for ASEditableTextNode
UITableViewCell traverses through all its descendant views and adjusts their background color accordingly either to [UIColor clearColor], although potentially it could use the same color as the selection highlight itself. After selection, the same trick is performed again in reverse, putting all the backgrounds back as they used to be. But in our case, we don't want to have the background color disappearing so we reset it after highlighting or selection is done.
* Fixed bug in `ASEnvironmentMergeObjectAndState`
* New ASLayoutSpec methods for `setChild`/`setChildren`/`setChild:forIdentifier:` have been added to take in a trait collection.
* Added `setChild:`-like methods for ASLayoutSpecs take a traitCollection
* Fixed instances where nodes in a data controller were not getting their trait collections
* propagate traitCollection in ASDisplayNode on insertSubnode or addSubnode
