Diff Viewer in Pull Request does not handle CR as line separator correctly

I'm working on a Mac and still have files that use CR instead of LF as line separators.
It appears that your diff viewer can't handle this and sees such text files as one big line.

See here, for example:

https://bitbucket.org/garrypettet/fgscopebar/pull-request/1/retina-support-and-a-few-minor-fixes/diff\\
E.g, the "demo app/FGScopeBar Components/FGScopeBar.rbbas" file, which is a text file. A screenshot is attached as well.
