Git History Diff doesn't show the merge commit 7e75e5dd in the file history, but all others including merge commits 6bc5a388 & 80143d60 (see the screenshot below). Unless there are no commits 1a29104d & dd5b1d6e here, then the merge commit 7e75e5dd is unrelated and doesn't need to show up in the file history.

The history is using --simplify-merges underlining.

I've checked out with --simplify-merges, it does show up the merge commit 7e75e5dd as below. You might need to dig into it a bit?

λ git log --simplify-merges --format=oneline master -- **/assessment-form-select.component.ts

Same problem, but when I click the githd button, the merge commits shows. I think first it uses --no-merges, when I click the githd button it does not.
