Thanks for fixing this. Turns out the issue was really just a recent PR accidentally adding an extra 0 to the end of the link, which was missed in review. Still, the link has actually updated and the correct medium href just redirects to this new href anyway, so might as well link the current href now.

In the future, if you've opened an issue for something, please do not open a PR to close it unless you have been assigned the work by a maintainer, regardless of how complex the work is or isn't (as per our contributing guide). This is a standard practice for OSS contribution.
