Text Handling in QTextEdit behaves differently than other text editors

Did: Double click to the right of the centre of a word and drag past
the beginning of the next word but not as far as the centre of the
next word.

Expected to see: I expected two words to be selected, because the
double click selection drag region overlaps a part of two words. This
is how most text editors / platforms and web browsers work.

Got instead: Only the first word was selected. The second word is not
selected until the mouse is dragged past its MIDDLE. I would not
expect there be different rules associated with the start end point of
the double click drag region and the current end-point.

I would like to see an option added to the QTextEdit class which makes it behave in the same way as other text editors e.g. notepad in Windows.
