- added tests for all 4 cases: output to string or into element vs first param contains link or not
- cleaned up logic - skip HTML entity encoding only if we can ensure insertion to text node / when output to string, we always encode
- DOMpurify sanitizes gopher, ws & wss links, which we previosly had tested for
apart from resolving conflicts:
- added missing docs
- inlined functions that were used in only one location
- updated unit test to support all previews
- fixed a regression that displayed the preview even when there was no preview and too early
