Text rendering glitches in combination with loader and elide

Text is painted when it's not expected if:

1. A loader fills a parent item with dimensions 30x30.
2. The loader sourceComponent is a Text with a right padding of 30. In this case Text content width should be reduced to 0.

In contrast this doesn't happen if the text is not used with a Loader. This is demonstrated in the attached example. If the parent item is clicked and it's width changed which forces a
repaint of all its children, the Text is now corrected and effectively disappears.

A similar issue can be seen when margins are used which is demonstrated in the attached example as well.

Steps to reproduce the issue:

1. Run the attached project
2. Click on the parent item (rectangle with borders) to see the text disappear when parent is resized
