Incorrect HtmlBlockMarkerBlock token detection

[tewnn]

1. Input <my_self_closing_tag/> or <my_self_closing_tag/> text <my_self_closing_tag/> is parsing like a single HTML_BLOCK_CONTENT.
2. Input A <my_self_closing_tag/> is parsing as TEXT(A), WHITE_SPACE, HTML_TAG(<my_self_closing_tag/>).
3. Input A <my_self_closing_tag/> text <my_self_closing_tag/> is parsing as TEXT(A), WHITE_SPACE, HTML_TAG(<my_self_closing_tag/>), WHITE_SPACE, TEXT(text), WHITE_SPACE, HTML_TAG(<my_self_closing_tag/>).

The first inputs should work the same way as samples 2 and 3.
