[Bug] Unable to navigate back after I click any file on extension's sidebar

[ShiftWatchOut]

Describe the bug Unable to navigate back to the file where I just browse.

To Reproduce Steps to reproduce the behavior:

1. Open any Github repository that contains more than one file, and wait until the extension loaded.
2. Click a file in Git-Master sidebar.
3. Click a different file in Git-Master sidebar.
4. Navigate back with any approach you know, including touching ⬅️ button the browser offers, typing history.back() in dev tool console, or slip two finger on touchpad.

Expected behavior I expect to be able to jump back, like this extension behaves on other platform.

Updating pjax to the newest version should fix this, but after doing so, your extension crashed after navigating back on Github
