===Crash occurs===
Reproducible with: 2017.4.33f1, 2018.3.14f1, 2018.4.10f1, 2019.3.0b5, 2020.1.0a7
Reproducible with:
iPad Pro 12.9" (iOS 11.2.1)

We're seeing a major resurgence of this in 2019.2.21f1, which previously fixed this issue. 12k out of 900k users crash (worldwide), and 87% are iOS 15/16.
I vote this issue = REGRESSED

Can confirm, not fixed in 2018.4.14f1.
Claiming it is fixed in 2018.4.X is misleading.
