tags doesn't match

[PPCM]

The behaviour with tags is strange.

For example:

With the following code

    steps:
      - name: checkout code
        uses: actions/checkout@v2

      - name: Version match
        uses: actions-ecosystem/action-regex-match@v2
        id: version-match
        with:
          text: ${GITHUB_REF#refs/tags/}
          regex: '^(.*)'

With the tag '1.2.3', it matches '1.2.3'

But with the following code

    steps:
      - name: checkout code
        uses: actions/checkout@v2

      - name: Version match
        uses: actions-ecosystem/action-regex-match@v2
        id: version-match
        with:
          text: ${GITHUB_REF#refs/tags/}
          regex: '^([0-9]*)'

Still with a same tag, it matches ''

And finally with the following code

    steps:
      - name: checkout code
        uses: actions/checkout@v2

      - name: Version match
        uses: actions-ecosystem/action-regex-match@v2
        id: version-match
        with:
          text: '1.2.3'
          regex: '^([0-9]*)'

It matches '1'

Any idea why?

There's no dots in ^([0-9]*) but 1.2.3 got dots.
