If a PR contains a commit with a submodule rename, then the diff is not showing in Bitbucket UI

#!python

$ git init
$ echo 'hello world' > foo
$ git add foo
$ git commit -m 'initial commit'
$ git submodule add url_of_another_repo
$ git commit -m 'add submodule'
$ git remote add origin url_of_repo_in_bitbucket
$ git push origin master

$ git checkout -b branch1
$ git mv name_of_submodule name_of_submodule2
$ git commit -m 'rename submodule'
$ git push --set-upstream origin branch1
