* Go to math mode
* write a^2 and then mark it and copy it with <ctrl-c>
* if you paste it again behind the original a^2, everything is fine and
the cursor ends up behind the pasted element.
* However, if you paste it e.g. into the superscript of the original
a^2 , then the cursor ends up before the pasted object and inside the
logical box, which is very annoying for navigation.
* The same happens if you copy a fraction \frac{a}{b} and paste it into
any super or sub-script or into any (de)nominator of another fraction.
* Probably the bug is not restricted to these examples.
