Looks like as a workaround I can open the diff in the Web IDE, and have whitespace rendering enabled there. But ideally this would be in the browser, where I'm navigating the review files and adding comments. ### Intended users Developers, Code Reviewers ### User experience goal The user should be able to turn on / off rendering of whitespace in the file browser for merge requests / diffs ### Proposal Add option for users to enable rendering of whitespace, leave turned off by default. ### Links / references <!-- Label reminders - you should have one of each of the following labels.
