New Image Dialog - Alignment is not persisted

Preconditions:

• Enable the Image Dialog from the WYSIWYG Editor section in the Wiki Administration.
• Optional, create a custom image style to be used with 'Adjustable alignment' set to 'Yes' and 'Default Alignment' set to 'Center'.

STEPS TO REPRODUCE

1. Edit a page containing some text
2. Add an image within the text (from toolbar, click on 'Image' and upload any image or select one from the existing images)
3. Click on Advanced tab and select an Alignment (e.g. Center), or select the custom image style from Standard tab to be applied

EXPECTED RESULTS

The image is added on the page with the chosen alignment (e.g. centered).

ACTUAL RESULTS

The chosen alignment is not applied to the added image.

When double clicking on the image > Advanced tab, the alignment is set to 'None', although the Center alignment was chosen and in Standard tab the custom image style is selected.
