Case-sensitivity with ~ and //

[quasiTriestino]

In vanilla Emacs (30.0.5), I have the following in my init.el to allow for case-insensitive searching:

(setq read-file-name-completion-ignore-case t
      read-buffer-completion-ignore-case t
      completion-ignore-case t)

When vertico is loaded, after invoking dired from my home folder, entering downloads TAB RET (with a lowercase "d") will send me to a dired buffer for ~/Downloads as expected.

However, if I invoke dired from any other folder (for example, from inside ~/.emacs.d) and enter ~/downloads TAB RET (again with a lowercase "d"), I get the following error: No such file or directory, ~/downloads/. I get similar results with find-file and when using // for root.

Performing the same steps in vanilla Emacs without vertico loaded sends me to a dired buffer for ~/Downloads.

Am I missing some customization step in order to allow vertico to handle case-insensitive searches when using ~ or //? Are is there some additional tab-completion step I should be performing?

Thanks for any help and for the great package!
