Non http(s)-links are not working in Issues (anymore)

Summary

In Issue-previews and on wiki pages are non http(s)-links clickable but in issue description not.
By now comments seems to have the same issues

One example for such links is this one which you cannot click: x-devonthink-item://90909FA9-FA9D-4650-BDA8-6E6697B0DF15

It also occurs when using the link function (same link as above) in markdown.

In the past they were clickable and we added links to our database in every ticket, which are now not clickable anymore.

Steps to reproduce

  1. Issue occurs on selfhosted GitLab-instance and on gitlab.com since (approximately) GitLab 13.4 or 13.3. Occurs on Firefox (Android and macOS) and Chrome (macOS).
  2. Start creating an issue.
  3. Add a non http(s)-link to the description (e.g. x-devonthink-item://90909FA9-FA9D-4650-BDA8-6E6697B0DF15) (in preview is the link clickable).
  4. Create the issue.
  5. The link in the description is not clickable.

Example Project (this issue is the the example)

Clicking on this link is not possible: x-devonthink-item://90909FA9-FA9D-4650-BDA8-6E6697B0DF15

But on this one it is possible: https://google.com

Code of above lines:

Clicking on this link is not possible: x-devonthink-item://90909FA9-FA9D-4650-BDA8-6E6697B0DF15

But on this one it is possible: https://google.com

What is the current bug behavior?

You cannot click non http(s)-links in issue descriptions.

What is the expected correct behavior?

You can click non http(s)-links also in issue descriptions. As you can do in the first comment below: #275975 (comment 440538500) Comments are also not working anymore


Ignore: testing editing description

Link to DevonThink as a bare link: x-devonthink-item://some-item

Link to DevonThink as a markdown link: (same link as above) in markdown.
