If I try this:

<<fnote """My note must mention <<ref author1999title>>""" >>

the <<showfnotes>> macro gets confused, and the wikified result is:

<$let output=My note must mention [author1999title>] </li>

Is this a problem that can be solved?

Yes, this is a limitation. The problem is <<fnote and >> are used as delimiters here. when you use <<...>> inside <<fnote ... then showfnotes get confused.
The solution would be to recursively look for any number of >> closing delimiter.

For example <<fnote """My note must mention <<ref author1999title>>""" >> does not work, but
<<fnote """My note must mention <$macrocall $name=ref tid=author1999title>>""" >>works fine.

To myself:
The output macro can be modified to address this.
