Pasting and undoing in the Find popup can modify project code

On Windows, pasting into the code editor's floating Find popup can insert or replace text in the underlying code instead of entering the search text. The reporter also describes method names changing. Pressing Ctrl+Z while the Find field is focused can then undo an unrelated earlier project change, such as a method or class rename, including changes outside the visible editor.

Paste and undo in the Find popup should affect only the focused search field. They must preserve project source, declarations and unrelated undo history.
