Link to create changesets does not set file name and contents

[tpluscode]

In our GitLab, the query strings are ignored. When I click the link which looks like {BASE}/new/gzip?file_name=.changeset/ninety-parrots-divide.md&file=---%0A%22%40zazuko%2Fmymuseum-pipeline%22%3A%20patch%0A---%0A%0Afeat%3A%20gzipping%20output%0A

The editor opens blank

We are running v16.11

If you found any source, feel free to PR, I don't know what's the new query name.
