What you did:

Navigated my README.md on GitLab using VoiceOver on Mac.

What happened:

When focused on the emoji links, the SR announces the links with the title of the emoji, instead of the actual contribution type, which is largely unhelpful for someone using AT.

Problem description:

So, after further investigation, it looks like this issue is probably with GitLab itself. In particular, their <gl-emoji> component is using a title attribute which overrides the <a> tag's title. GitHub's <g-emoji> component does not do this.

I've filed an issue on GitLab for reference: https://gitlab.com/gitlab-org/gitlab-ee/issues/8622
