The functional confusion stems from the modification of basic copy/paste, not from the removal of data from the address bar.
is an example where there's a hard problem that materializes out of thin air as a result.
WYSIWYG copy/paste is bound to break at some point. But it should be pushed as far as possible to complex tasks not floated into the most abstract action - copying an address. The issue is conceptual, it is unrelated to implementation.
