Searchbar on navbar broken on Google Chrome

[guilpejon]

I noticed this error in the documentation page, search bar section (http://materializecss.com/navbar.html).
I'm attaching a picture of the error below, but basically the search input (when clicked) is floating above the place where it was supposed to be, and I was able to reproduce this error in my project too.

Digging around the HTML, I noticed that this can be fixed with two height: 100%. One on the <form> tag, and another one on the <div class="input-field"> right below it.

Don't know what is the right way to fix this, but I can try to add this solution to the code if someone points me the way.

BTW, I'm using version 51.0.2704.84 (64-bit) of Google Chrome, and the form works fine on Safari and Firefox.
