Web editor modify newlines

Since switch from satellites to rugged in web editor we have a problem with web editor changing newlines:

Before we had flag git config --global core.autocrlf but it does not respected by rugged commit.

Example of file edited with web editor recently - gitlab-com/www-gitlab-com@94bf9a74
