Feature request: Show diff between current and target branches in per-file diff view

[Frederick888]

At the moment in per-file diff views, it shows the difference from the common ancestor between current and target branches [1].

This gives different results from GitHub web. It'd be nice if this can be configured to head of target branch. (We all have to work with someone who just loves merging master/main into PR branches, don't we ;) )
