Moving a page from one Space to another adds the old space PREFIX to any content in square brackets, even if the square brackets are escaped

I had content like this

[installation] At the moment we are using the "standalone"

After moving the page from the Space with key FOO to the Space with key BAR the content is now like this

[FOO:installation] At the moment we are using the "standalone"

And obviously FOO displays on the page. I want to get the square brackets on the page content, as it is my way of marking the paragragh.
