I am using a multi branch pipeline. The branches name contains a /. 
Example: branch name is feature/ABS-62317

When I am in a build in a multibranch pipeline in normal view, the URL is like this:
job/<MyJobName>/job/feature%252FABS-62317/<MyBuildNumber>/

When I am pressing Open Blue Ocean I am redirected to:
blue/organizations/jenkins/<MyJobName>/detail/feature/ABS-62317/<MyBuildNumber>/
The problem is that this will result in 404, page not found.
The correct link should've been
blue/organizations/jenkins/<MyJobName>/detail/feature*%2F*ABS-62317/<MyBuildNumber>/

So replace the / in the url of the branch name with %2F
Finally, after replacing the text and seing the build pipeline in ocean blue mode, if I press next/previous(the arrows from top left) and then refresh, I am redirected again to the 404 page.
