bug#58027: 29.0.50; Problem with image-crop in Customize buffer

[Mauro Aranda]

After emacs -Q:
1. Evaluate the following:
(defcustom foo nil "..."
    :type 'boolean)
2. M-x customize-option RET foo
3. Go to the arrow, the custom-visibility widget
4. Type c (this could be a simple mistake, like it happened to me)
5. Type q or C-g (since you didn't mean to crop anything)
6. Now the tag and the widgets to customize the option are all gone.
This shouldn't happen.
