Avoid triggering search when s is pressed on active input.

Problem

We're trying to add a custom search element to mdbook docs, and the default search logic keeps stealing the s key when we try to type it into the search box of our alternate search.

Steps

1. To go https://test-builds.readthedocs.io/en/mdbook/
2. Press / to bring up our custom search
3. Try to type a word with s in it.

Possible Solution(s)

The mdbook search logic should not fire when there is an input element that has focus.

It seems like https://github.com/rust-lang/mdBook/blob/master/src/theme/searcher/searcher.js#L319 should be checking for input types as well as textarea types?

Version

mdbook v0.4.43

It should already be checking for input via the check on e.target.nodeName. Maybe attach a debugger and see why that isn't included?
