Pull Request comparing different lines when "Whitespace changes" option is enabled vs disabled.

[Abirami Mahadevan]

It almost seems like Bitbucket is confused when comparing large files with a lot of similar looking comments. When "Whitespace changes" are enabled, for example - line 30 in the old file is compared to line 45 in new file. When "Whitespace changes" are disabled - line 30 in the old file is compared with line 35 in the new file - which is what I was expecting to see.

I do get a notification when "whitespace changes" are enabled that the diffs are too large and if I really want to see the diffs. I have to click a button that I am sure and that I want to view the diffs. 

Using Bitbucket server version 7.1.1.

It almost seems like the pull request is showing "wrong" diffs and is misguiding the reviewer.  

Has anyone else experienced this? Any ideas on how to fix it?
