Centered image is displaying a scroll bar on the document content if it's the only content in the page on Chrome

Steps to reproduce:

• create a page with the following syntax (replacing the image name with an image you have):

  [[image:xwiki-o.png||data-xwiki-image-style-alignment="center" height="300" width="300"]]
  
  

• note that this syntax is obtained by adding an image from the wysiwyg editor and choosing the center option in alignment options
• note: no image style is configured on the instance, it's the default setting of styles, shipped with the standard distribution
• save
• view the page

Expected result:

• the image is displayed centered on the page, with no scroll bars

Actual result:

• there is a vertical scroll bar on the content:
  

This doesn't seem to reproduce on Firefox.
