1. emacs -Q
2. C-x f /sudo::~/ (alternatively use an ssh path of a similar form)
3. Open the completion buffer by pressing ?
4. Click/select a directory in the completions buffer

The resulting path looks like this:

/sudo::~dir/

The underlying issue is that somewhere a wrong completion boundary is
reported by the Emacs completion table for non-normalized file paths
which contain ~. This issue also affects other completion UIs. The issue
is present on both 27 and 28.

Well, nothing left to do then, I'm closing the bug.
