I have a workflow to bump our repo tag and it will be triggered once changes are coming from any files under production folder. See my snippets below.

# bump-my-tag-version.yaml
name: Bump my tag version!
on:

push:

branches:

- 'master'

paths:

- '**/production'

- '!excluded_dir/production'
jobs:

bump-version:

runs-on: ubuntu-20.04

...

I have a few directories that has production folder as seen below.

excluded_dir/production
included_A/some_dir/production
included_B/some1/some2/production
included_C/some1/some2/some3/production

When I merge my changes to my main branch (master), it did not trigger the workflow. Which I expect it should because this filtering has already been implemented. See this post from GitHub.

Is this a bug or something is wrong with my implementation?
