rustdoc with a `?search=foo` URL, stuck at "Loading search results..."

[SimonSapin]

Steps:

• Navigate for example to https://doc.rust-lang.org/nightly/std/?search=string
• See the page show "Loading search results..."
• Results are never loaded
• In devtools, the JavaScript console shows "ALIASES is not defined" with the details below.

ReferenceError: ALIASES is not defined[Learn More] main.js:1016:1
	execQuery http://localhost/rust/main.js:1016:1
	execSearch http://localhost/rust/main.js:1319:31
	search http://localhost/rust/main.js:1404:25
	startSearch http://localhost/rust/main.js:1548:13
	initSearch http://localhost/rust/main.js:1552:9
	<anonymous> http://localhost/rust/search-index.js:8:1

Grepping shows that ALIASES is defined in aliases.js. This file is included with <script defer src="../aliases.js">. This defer is presumably problematic for the search-during-initial-load case.
