Paste into a Replace Box doesn't work

In the formula editor, if I open up a Replace Box with Ctrl-H and try to paste into one of the lines inside the box with Ctrl-V, the replacement text goes into the formula at the cursor position instead of into the Replace Box.

This is not the behavior that I had expected

Noted, thanks!

Hi all,
The same happen with ctrl+F in formula writing, i do a ctrl+C in a piece of code and after i do ctrl+F and ctrl+V but the paste is again in formula editor and not in the find-window.
Ciao
