Could you verify if this fixes #44740?

Indeed it does.

@bors r-

Not your fault, but unfortunately a test case is invalid, causing failure after the bug is fixed. Please apply the following diff:

Is it possible for travis to run those tests automatically? They seem like they will be pretty fragile.

[kennytm]

@ollie27 Those tests should be run automatically, but it seems the CI docker image is missing nodejs.

[01:37:12] No nodejs found, skipping "src/test/rustdoc-js" tests
[01:37:12] Build completed successfully in 0:56:39
