Clicking "back" after viewing commit details sometimes lists commits with incorrect order

Steps:
1) visit http://coop.stb.intra/stash/projects/someProject/repos/someRepo/commits
2) click on any hash of a commit which the current logged on user did not make
3) click "back" in the browser

Expected:
the same list of commits as shown in step 1.

Actual:
Sometimes, a pseudorandom list of commits are shown, with incorrect dates. The order is always the same.

Workaround:
Instead of clicking "back" in the browser, always click the "Commits"-tab to get back.
