I was hit with a couple of bugs: hx-on not properly de-initializing,
with a workaround in 43fffb68 and properly fixed with version 1.9.2;
and elements with naked hx-trigger did not work with hx-boost, as i do
for the tag inline form, fixed in 1.9.1.
The other bug fixed in 1.9.1, play well with other libraries that also
use the window.onpopstate, did not affect me, i believe.
