Thank you very much. We've made a change. A comparison of the behavior before and after the changes is below.

### On MAcOS.
#### State before our changes .:
- in a standalone label with an icon without text, VO says Image;
- in a standalone label with an icon with text VO speaks the text of the label;
- If a label without text with an icon is in the table VO says "Empty cell".

#### If you add just a role change:
- in a standalone label with an icon without text, VO says Image;
- in a standalone label with an icon with text VO speaks the text of the label;
- In the table for a label with an icon without text, when navigating horizontally, VO does not say anything;
- In the table for a label with an icon without text for vertical navigation, VO says "image cell".

Unacceptable option.

#### With a complete fix:
- in a standalone label with an icon without text, VO says Image;
- in a standalone label with an icon with text VO speaks the text of the label;
- In the table for a label with an icon without text, for any navigation, VO says "image".

### ON Windows.

#### State before our changes:
- in a standalone label with an icon and text, the label text is spoken;
- in a standalone label with an icon without text, the label is skipped;
- In the table, a label with an icon without text is not spoken, the column heading is spoken.

#### With full patch:
- in a standalone label with an icon and text, the label text is spoken;
- in a standalone label with an icon without text the "Image icon" is spoken;
- In the table, a label with an icon without text is pronounced as "Image".
