* Make htmx IE11 compatible again + tests IE11 compatible
* IE11 compatible handmade socket mock for ws-ext tests
* Fallback when xpath isn't supported, hx-on wildcard now working on IE11
* Merge remote-tracking branch 'upstream/relative-url-in-hx-boost' into ie11-compatibility
This resolves a bug when file system URLs are used on Windows. It
reverts part of a previous change where URLs were normalized prior to
the request in order to reduce key collisions in the history cache.
Because htmx's history cache is based entirely on response URLs, not
request URLs, I am reasonably confident that reverting this line doesn't
affect that optimization at all, but in any case it causes a bug which
is more important.
* Normalize URL used as a cache key for history, without breaking IE.
* Update test `boosted element hx-disinherit sanity check` to check that the fully resolved href of the boosted element matches request.detail.requestConfig.path
