* Failing test for oob-swap within web components
* hx-swap-oob respects shadow roots
* Lint and type fixes
* fix jsdoc types for rootNode parameter
* Fix for linter issue I was confused about before
* oob swaps handle global correctly
* swap uses contextElement if available, document if not
Previous a commit made swapOptions.contextElement a required field. This
could have harmful ramifications for extensions and users, so instead,
the old behavior of assuming document as a root will be used if the
contextElement is not provided.
* rootNode parameter is optional in oobSwap
If not provided, it will fall back to using document as rootNode. jsdocs
have been updated for oobSwap and findAndSwapElements accordingly.
* Add config option to ignore nested oob swaps
* Fix oobElement root check
* Save config between tests; repeat some tests with different configs
* Add tests for oob-swaps in html, body tags
* Don't unnecessarily change const to var
