Horizontal scrolling broken in 0.32.0-rc.0

[rozele]

Horizontal scrolling example is broken in UIExplorer.

Confirmed this is also an issue for 0.31.0.

Turns out this is related to the update to Facebook.CSSLayout v2.0.1-pre. We may need to revert 104aa49 (cc @rigdern)

@rigdern, it looks like if you call CalculateLayout() on the horizontal scrolling content, it works okay, but I'm not sure the right infrastructure for that. In the meantime, I'm going to revert 104aa49 and we can work on integrating it in a future release.

Probably there is something very simple that we can do to signal to the CSSLayout engine that the width measurement mode should be undefined for horizontal scrolls, thoughts?

@rozele I can take a look at this later today.

Just to double check, are you using the same UIExplorer code used in the iOS and Android versions of 0.31.0? After updating the layout engine, Facebook had to make some tweaks to the UIExplorer app to fix bugs due to differences in the layout engine implementation. For example, react/react-native#8248 was introduced and was fixed by react/react-native@dc5b490.

@rozele What's the latest news on this? I saw that this bug got closed without a corresponding bug being opened for upgrading the layout engine. Should I still look into this or did you figure it out? If I need to look into it, are there instructions somewhere for running the UIExplorer app? Also, I'm still curious to hear an answer to the question in my earlier comment.

I didn't open a new bug yet, but, yes, this still needs to be investigated. I think there's a README in the Examples folder for how to run the UIExplorer (or it may be the main README).
