… pixels Summary: Fixes facebook#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).

Summary:
Fixes #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/FitContentconstraint. This means that if a node is given a zero width, and Yoga later measures with withFitContent, 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).
