Empty Tooltip Text Displayed on Images

[segun-codes]

Describe the bug:
As observed by yuri-karelics, when image is not configured to have tooltip, the tooltip is shown as empty.
Proper behaviour is to disable tooltip completely if not setup and no object, suggesting tooltip text is missing, should be shown.

Reproduce the behavior:

1. Run the program on dev server (use command: npm run serve:dev).
2. Load the example URL http://localhost:8081/examples/select.html and place mouse on any of the images.
3. You should observe an object suggesting no tooltip text is available.
