Expected behaviour

File correctly opened

Reproducible with any Android version and backend.

Start with the text-preview flow and the Android TextView, ScrollView, and StaticLayout measurement frames shown in the stack trace. Reproduce the crash with a roughly 30 MB TXT file, then verify that large text opens without an OutOfMemoryError on Android versions and backends.
