When the big_pipe module is enabled I cannot open or expand any of the variants for any of my pages.

I attempted some debugging in page-manager-ui-page-variants.js and simply found that the active class is not getting applied for the variant list items to expand. It wasn’t consistent, but sometimes it gets as far as getting within the if statement but other times not.

I figured it out by progressively disabling administrative or back-end modules and the problem was resolved when disabling Big Pipe.

Moving the library attach to the preprocess function for the page manager wizard tree template seems to solve this issue.

There is another issue tough with switching variants that is solved in another issue at https://www.drupal.org/node/2868216 that is also required for it work work properly.
