Subject: 28.2; string-rectangle cancel can leave garbage from preview
Date: Sat, 14 Jan 2023 17:00:46 -0800

Steps to reproduce, starting with 'emacs -Q':

1. Go to the scratch buffer OR create a new
buffer with 'C-x b foo RET'. (Tested both ways.)
2. Press 'C-SPACE' or 'C-x SPACE' to set the mark. (Tested both ways.)
3. Press RET.
4. Press 'C-x r t' (string-rectangle), then type 'foo', but do NOT press
RET! A preview will appear in the original buffer, showing two instances
of the string "foo", as expected.
5. Press 'C-x o' or click in the main window (tested both ways). This is
the step which triggers the bug!
6. Press 'ESC ESC ESC' to cancel.

Expected results: the preview instances of the string "foo" in the
original buffer should disappear, as they do if you skip step 5.

Actual results: the preview instances of the string "foo" do NOT
disappear, and cannot be removed by any obvious means. Attempting to
delete them simply deletes the newlines between them. Nor can you return
to the minibuffer via 'C-x o'; the string-rectangle command has truly
been cancelled.
