Android: deleting text in QPlainTextEdit with predictive text turned on

To reproduce: run the application example

When a paragraph spans several lines, deleting from the end of the paragraph will leave junk on the screen when the editor re-wraps the text.

This is a regression from Qt for Android 5.2.1

This has only been reproduced with QPlainTextEdit so far. This does not happen with QTextEdit or the TextEdit item in Qt Quick.
