QPlainTextEdit: draw placeholder text correctly when it wraps
382faed introduced placeholder text to QPlainTextEdit. But the code
relied on the text begin short enough to fit inside the width of
the text edit. If the text was longer, and therefore wrapped, drawing
artifacts would show.
This patch will listen for text changes and check if the
placeholder text should show or not, and if so, issue a full update
to ensure that the whole placeholder text is either fully drawn
or hidden. And then we allow to the placeholder text to be drawn
inside the full rect of the text edit.
Task-number: QTBUG-61875
