* [core] Add html/convertLazyLoading($dom)
Looks for lazy-loading attributes such as 'data-src' and converts
them back to regular ones such as 'src', easier for RSS readers.
It also converts <picture> elements to plain <img> elements.
* [core] Document html/stripRecursiveHTMLSection()
Add documentation for that function (no code changes).
* [WordPressBridge] Use convertLazyLoading()
* [WordPressBridge] Unwrap image figures
<img> inside <figure> may not display on RSS readers.
This converts them back to <img>, without losing caption if present.
* [ZDNet] Convert lazy loading images
* [code] html/stripRecursiveHTMLSection: Fix typo
