Hello,

It's almost the same as described here:
https://mail.gnu.org/archive/html/emacs-orgmode/2020-12/msg00199.html. BUT,
this only comes into play in the following case:

Suppose you want to complete an org-capture template with this: “%^{Title}”.
When you call this capture, the minibuffer allows you to select the title
(in the minibuffer). But, if you want to capture "from" this minibuffer, it
crashes org-capture with the error (just after the choice of the second
template) :
org-capture: Capture template 'u': Can't expand minibuffer to full frame.

Concrete use case: capturing an org-roam node (and complete the title),
trying to insert a node that doesn't yet exist (and therefore reopening
org-capture) in the title of the first capture process.

Thank you in advance for your reply.
