Adding head support to the html tag

[fullstackplus]

Due to the way my markup is structured, I have multiple HTML (ERB) templates starting with the body tag. So instead of adding hx-ext="head-support" on each and every one of them, I want to put it on the html tag which is declared once in my global layout file.

Will this work? I've been searching the docs but all examples use the body tag for hx-ext / hx-boost.
