A host page can define a tag name before our bundle loads, and the first definition wins. DX Life's own
/js/doxa-simple-map.js defines <doxa-map> and <doxa-simple-map>, so on those pages our guarded define was
skipped and the page drew the host's element under our name.
- The doxa-simple-map bundle now defines <dxm-simple-map>, DX Maps' own name, first. The manifest, the leaf
pages and the gallery mount it (generate-tree reads the first define).
- <doxa-map> and <doxa-simple-map> are defined only when the host asks: data-legacy-tags on the bundle's
<script>, or window.DXM_LEGACY_TAGS = true before it loads.
