Idea from @Fomafix at https://gerrit.wikimedia.org/r/507067:
The module 'mediawiki.searchSuggest' has dependencies on the following modules:
- jquery.getAttrs
- jquery.highlightText
- jquery.suggestions
- mediawiki.searchSuggest
- user.defaults
These have a combined size of 24 KB (24,613 bytes, minified but before gzip)
These modules must not already get loaded on page load. Some modules may
already get loaded on page load by other dependencies from extensions.
Looks like this could make a pretty big win. As Fomafix says, some of these dependencies will still be pulled in by other code, but worth exploring.
