"ignore-from-file" not taking into account gitignore exceptions

[drAlberT]

Using ignore-from-file .gitignore seems to wrongly handle the case like the following:

.*
!.checkmake
!.editorconfig
!.gitignore
!.gitlab/
!.gitlab-ci.yml
!.gitleaks.yml

With the above config no error is reported in the .gitlab-ci.ymlfile, while it works perfectly removing ignore-from-file .gitignore directive in .yamllint.yml

Could be the problem here? Isn't expected to have lines instead of the entire file? https://github.com/adrienverge/yamllint/blob/a68c3aa69e298ea20bdfb51ac388d5bfc4c347aa/yamllint/config.py#L113C78-L113C78
