Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1823 X-link: https://github.com/facebook/react-native/pull/52348 Fixes https://github.com/facebook/yoga/issues/1819 Yoga has a fast path when measuring a node, if it thinks it knows its dimensions ahead of time. This path has some eroneous logic, to set both axis to owner size, if *either* will evaluate to zero, while having an `YGMeasureModeAtMost`/`FitContent` constraint. This means that if a node is given a zero width, and Yoga later measures with with `FitContent`, its height will become the maximum allowable height, even if it shouldn't be that large. We can fix this, by only allowing if both axis are this fixed case, instead of just one. This bug has existed for about a decade (going back to at least D3312496).

yoga-layout
This package provides prebuilt WebAssembly bindings for the Yoga layout engine.

Usage
import {Yoga, Align} from 'yoga-layout';
const node = Yoga.Node.create();
node.setAlignContent(Align.Center);
Objects created by Yoga.<>.create() are not automatically garbage collected and should be freed once they are no longer in use.
// Free a config
config.free();
// Free a tree of Nodes
node.freeRecursive();
// Free a single Node
node.free();
Requirements
yoga-layout requires a toolchain that supports ES Modules and top-level await.
If top-level-await is not supported, use the yoga-layout/load entry point instead. This requires to load yoga manually:
import {loadYoga, Align} from 'yoga-layout/load';
const node = (await loadYoga).Node.create();
node.setAlignContent(Align.Center);
