Image reference is not updated after page rename when parent page name contains special characters

I did the following test on 18.4.0:

• create top level page "red"
• created child page "green" under "red"
• uploaded mflorea.jpeg to "green" page
• created child page "blue" under "green"
• inserted mflorea.jpeg and a link towards "green" in the content of "blue"

  [[image:red.green.WebHome@mflorea.jpeg]]
  
  [[green>>doc:red.green.WebHome]]
  

• renamed "red" to "pink"
• the content of "blue" became:

  [[image:red.green.WebHome@mflorea.jpeg]]
  
  [[green>>doc:pink.green.WebHome]]
  

As you can see the link target has been updated while the image source has not. The page names I used didn't have any special characters. Note that the problem stays if I use attach:red.green.WebHome@mflorea.jpeg as image reference, i.e. it doesn't matter if the resource reference is typed or not.

was actually meant to be

[[image:example-page.WebHome@example.png]]

this can't work for referencing the image from the parent page. You need:

[[image:page-name.example-page.WebHome@example.png]]
