### Claim evidence

I am the owner of the GitHub account https://github.com/xiao-linxin (created 2016-07-11),
and I am also the owner of the VS Code Marketplace publisher "xiaolinxin"
(https://marketplace.visualstudio.com/publishers/xiaolinxin).

- Extension on VS Code Marketplace: xiaolinxin.markdown-editor-xlx
https://marketplace.visualstudio.com/items?itemName=xiaolinxin.markdown-editor-xlx
- Extension repo, owned by the same GitHub account that opens this issue:
https://github.com/xiao-linxin/vscode-markdown-editor-xlx
- Already published on Open VSX:
https://open-vsx.org/extension/xiaolinxin/markdown-editor-xlx

Note: the namespace "xiaolinxin" differs from my GitHub username "xiao-linxin";
both belong to me. My Eclipse account "xiaolinxin" is linked to this GitHub account:
https://accounts.eclipse.org/users/xiaolinxin/linked-accounts

I have already logged in to Open VSX with this GitHub account — the extension page
shows publishedBy: xiao-linxin.

Thanks!
