Trying to expand more lines in the pull request diff, tooltip and spinner are working but lines aren't expanding. That is, it just doesn't do anything.
Error reproduced on https://bitbucket.org/atlassian/aui/pull-request/244/add-experimental-sortable-tables-to-the/diff with Chrome and Firefox latest on win7. See screenshot.
Means I can't actually see enough context to process the PR.
