White spaces at the end of Arabic text line break the Text and TextEdit horizontal alignment and selection

Qt text painting routines currently draw the wrapped multi-line right-to-left incorrectly. It seems that the white spaces at the end of the text line affect the positioning (alignment, painting of the text selection region) of the whole text line, breaking the text painting. See attached screenshots and QML files for an example. The problem affects both the Text and TextEdit elements.
