qiime tools view: Snap-installed browers can't open /tmp

[ebolyen]

Bug Description
Snap packages seem to possess their own /tmp directory, which means that our approach of loading the index.html from a tmp directory doesn't work as it isn't visible to the snap application.

It may be time to make qiime tools view use a localhost-only http server instead.

localhost-only http server instead.

I think this package does this.

Can we render .qzv files as index.html files, like a static site generator? Then we download and/or view the static HTML?
(If there's a better place to track this, please redirect me there!)
