Inline HTML void element makes the rest of the paragraph lose its Markdown syntax

When parsing markdown/1.2 content, an inline HTML element without a closing tag (e.g. <br>, <img ...>) makes the whole rest of the paragraph become a single inline HTML macro. That content is then re-parsed without the configured Markdown extensions, so wiki links, macros, strikethrough, etc. are lost.

Steps to reproduce

Parse:

a <br> [[Page]] ~~s~~ b

Result

onWord [a]
onSpace
onMacroInline [html] [clean=false] [<br> [[Page]] ~~s~~ b]

Expected

<br> is output as inline HTML and the rest of the paragraph is parsed as Markdown (wiki link, strikethrough).
