UX issues with internal links

Hello, I confirm that internal links are completely broken! @mejo-
I tried to make them work in every way is possible (and also encountered at least 5 different bugs and UI issues that I will list here as all are related to internal links broken).

1. About the Popup that appears clicking on a link

• UI To improve: it doesn't make clear where people should click as it has a preview with the same text of the link on the second line.
• bug: on mobile the button in the popup to copy link text is not visible as it goes too far on the right

2. Link inside a Callout box

• bug: if a put a link with Smart Linker (both Preview or Text-only mode) in the middle of a text inside a callout box, it "breaks" the box in 2 parts, one above the link and one under the link and the link seems outside of the box, in the middle.

3. About Preview and Text-only views

• bug: the link to another Collective page, created with Smart Linker, preview mode, is not clickable at all from both desktop and mobile view
• bug: every time I can see the long link (as simple text, not clickable) above the Preview box (this feels like clutter from UI point of view)
• bug: on mobile the preview box is so small that the link inside is not properly shown
• UI To improve: (In my opinion) The Preview view is too big and risks breaking the "visual balance" of the pages in Collectives, especially if links are inserted inline, in the middle of the text.
• Feature/UI To improve: In Text-only view I cannot add a Placeholder for the link (like in classic Markdown syntax) as I can do with the "Insert link" button, so I always have to see long links here and there in the middle of the text.
