Revert "Ensure %w and %# are also expaned in the 'Copy input' dialog"

That fix is not good enough because it makes '%w' being updated only
after keystroke instead of immediately . The issue of updating title is
actually a little more complicated than I have understood.

Revert it because the regression should influence more users than the
fixed problem does. Need to spend more time to find a better fix.




This reverts commit 1c1981501b6e3bcd433840bf36f7851f06772322.
