rustdoc: Pressing back after search doesn't reset <title>

[frewsxcv]

1. Navigate to https://doc.rust-lang.org/nightly/std/index.html
2. Type a query in the search bar (wait for results to appear)
3. Take note of the title of the search results
4. Press 'back' and notice how the title doesn't reset

Which browser are you using? It does work fine for me in Firefox 38 on Linux.

[frewsxcv]

Latest stable Firefox and latest stable Chrome on OSX 10.10

Doesn't reset for me on OS X 10.10.2 (Yosemite), Chrome 43.0.2357.130.

Doesn't reset here. Mozilla Firefox 38.0.5 on Manjaro Linux 0.8.13.

My browser probably cached an old version, now it doesn't reset on my setup, too.

This still happens for me, but that might be because #26732 hasn't been deployed yet

Should have been deployed to nightly, but it clearly hasn't:

Edit: hmm, actually it only landed a couple days ago... maybe hasn't made it.

This change just barely missed landing in the last nightly.
