Code review - how to get tree order to match diff order?

I’m using gitlab.com, and doing a lot of code reviews in the MR process.

The file order in the tree widget is consistent with the directory hierarchy. The order of the diffs on the main panel isn’t the same. Is there some setting or way of getting the two orders to be the same?

I largely review the changes in order of the diffs, effectively using using the scroll bar as sort of progress indicator. Often I need to navigate around all the changes to understand the interactions - for which I use the tree widget. The fact that the two file orders are not the same is distracting at best and often confusing.

Does anyone have any suggestions - some option somewhere? a different way for thinking about the review? should I submit a UX bug to gitlab?

Thanks,
Ian.
