wrong link (if text only) in publicly sharing collective (between collectives)

[Thatoo]

Describe the bug
Hello,
In collective, if I insert a link to an other collective, if I share my collective and open this collective in private mode (of my browser) using the skared link, then, the link to the other collective is either :

• ok if the link is set as "Show link preview" : it is possible to navigate between collectives
• wrong (needs to authenticate) if the link is set as "Text only".

For example if I open my collective in private mode using a public shared link :

the first link "Comment trouver un local" which is set as "Text only" will give me a private link so it's not possible to navigate between collectives :

but the the second link "Comment trouver un local" which is set as "Show link preview" will give me a public link so it's possible to navigate between collectives :

To Reproduce
Steps to reproduce the behavior:

• open collective A
• add a link to collective B set as "Show link preview"
• share collective A and get a public link
• open collective A in private mode using the public link
• clic on the link to collective B : it works

Then

• open collective A
• add a link to collective B set as "Text only"
• share collective A and get a public link
• open collective A in private mode using the public link
• clic on the link to collective B : it ask to authenticate, the link is wrong

Expected behavior
The link should be public in both mode "Show link preview" and "Texte only"
