"Changes since your last review filter" needs to ignore merge commits

[LondonRain]

Description

The "changes since your last review filter" also shows merge commits, where I updated my feature PR branch from the base branch. Those changes would not be shown when looking at all commits of the PR as they are not different to the base branch. The commit filter needs to ignore merge commits.

Do you happen to know the correct argument to git for it?
At the moment, we use git diff-tree --name-only --root --no-commit-id -r -z $BASE $HEAD to get the changed files between the two commits.
It will either be as simple as adding the correct argument to it, or it will be (basically) impossible.

Is that even the part you mean?
From your description, I'm not quite sure exactly what you're asking for:
Are you asking for

• not showing file changes in merge commits that changed in no other commit inbetween?
• not showing the Only show changes since the last review comparison button when the base commit is a merge commit?
• something else?

It's not about the general diff view on a PR but within the commit filter

This had two commits since my last review of which one was a merge commit to update the PR branch from its base branch.

Selecting the "Show changes since your last review" option than produces a diff where it includes ALL the changes from the merge commit, despite the files being identical on source and target branch. This makes the function pretty useless.
