Subject: bug#62679: 29.0.60; Bindings on `image-map` cause error on sliced images

From: Rah Guzar <[email-masked]>
Date: Wed, 05 Apr 2023 17:23:11 +0200

Dear Emacs maintainers,
  Starting from `emacs -Q`, post the following code into scratch buffer,

```
(let* ((image (create-image path-to-png 'png nil :mask 'heuristic))
       (rows (max 1 (1- (cdr (image-size image))))))
  (goto-char (point-max))
  (insert "\n")
  (insert-sliced-image image " " nil rows))
```
This inserts the image specified at the end of the buffer. The image
has a `keymap` text property which include binding for various
operations on images but moving point to the image and trying to use
any of these (e.g. `i +` to increase image size) results in the error,

Error running timer ‘image--change-size’: (error "No image under point")
