Image alignments are not taken into consideration in edit mode when replying to a comment or annotation

Steps to reproduce

1. Add a comment on a page
2. Click 'Reply' to add a reply to that comment
3. Click on 'Image' from toolbar
4. Select or upload an image
5. Click 'Advanced' tab
6. Select an alignment (e.g. Center)
7. Click 'Insert' button

Expected results

On edit mode, the image is displayed according to the alignment set.

Actual results

The image is displayed at the start (left) of the input area.

However, if the reply is added by clicking 'Add Comment' button, the image is displayed with the set alignment in view mode.

The same reproduces with replies to annotations.
