git-diff with .gitattributes in a bare repository

Question

I use gitea for storing my code and noticed that it doesn't obey .gitattributes when diffing.

Having looked into this it seems to be an issue with bare repos. I found some information on libgit2 that suggests using the GIT_INDEX_FILE environmental variable.

repo.git # GIT_INDEX_FILE=tmp_index git read-tree --reset -i testing-attributes
repo.git # GIT_INDEX_FILE=tmp_index git check-attr --cached --all ent/actions.go
ent/actions.go: diff: unset
ent/actions.go: merge: unset

This seems to work for check-attr but I can't seem to get it to work with git diff.

GIT_INDEX_FILE=tmp_index git diff c165f76c8c 71ecf0a90b

diff --git a/ent/action.go b/ent/action.go
index 7d4edbe..4b71332 100644
--- a/ent/action.go
+++ b/ent/action.go

The diff still displays changes in files that have the -diff attribute set on them. I would expect to see

diff --git a/ent/action.go b/ent/action.go
index 7d4edbe..4b71332 100644
Binary files a/ent/action.go and b/ent/action.go differ
