Wrong attachment displayed when overriding an attachment and viewing page

Reproduction steps:

• Create a page with an attachment named "foo.png" and the content:

  [[image:attach:foo.png]]
  

• Edit the page with a WYSIWYG editor, remove the image from the content and upload another one with same name "foo.png"
• Without saving or closing, open another tab and view the original page

Expected result:

• the original page should display the image originally attached

Obtained result:

• the original page displays the new image even so it's not saved yet
