<View /> doesn't recalculate it's size when a descendant <Text /> changes height due to wrapping following a device rotation

🐛 Bug Report

I believe I've found a bug in the View size calculation logic in React Native. In certain cases, the ancestor View fails to recalculate its size if a descendant <Text /> component changes in size due to a rotation and subsequent text (re)wrapping.

The following shows three states: initial, rotated, and back to original orientation. Notice that the fuschia view "grows" after returning to the original orientation.

Initial orientation

Portrait

Back to initial orientation

Speculative Analysis and Workaround

This appears to be an issue where an ancestor view caches a layout calculation and doesn't trigger a re-calculation when a nested Text component changes in size due to orientation changes.

After some playing around, we've figured out that if you "poke" any of the style properties that affect the view's style layout, the view will recalculate and be correct. We did this by toggling a state var upon rotation and then adding/removing a style object to the view's styles array that contained an extra paddingBottom that mirrored the existing padding on the view (basically we changed the style but the effect had no changes to the layout).

You can see a demo of the workaround by uncommenting the line of code below the FIXME comment in the code sample.

To Reproduce

See the code, but basically if you have a <ScrollView> that contains a container <View> which contains another <View> and then have a <Text> element inside that view... this layout bug will happen. I haven't been able to reduce this example further than that.

Expected Behavior

After rotating and going back to the initial orientation, the View should be exactly the same size.

Commencez par le dépôt de reproduction lié et reproduisez la séquence de rotation impliquant ScrollView, des composants View imbriqués et le retour à la ligne de Text. Lisez la logique de calcul de la taille de View décrite dans le rapport et comparez les orientations initiale, portrait et restaurée. Le travail est terminé lorsque le View ancêtre retrouve exactement la même taille sans le workaround de changement de style.
