Command menu: Tab file completion: no files proposed (I see ^I on Tab), but on Ctrl-D I see all files in the current folder

Hi, I tried with vim -u NONE --noplugin so looks like this is not related to a plugin or a config.

How it looks:

:e <here I press Ctrl-d and see all files>
README.md       ftdetect/       gvimrc          init.vim        mini.vim        plugin/         tmp/
colors/         ftplugin/       highlights.vim  lecture/        pack/           spell/          vimrc
:e READ^I^I # here I press Tab :(
