#render_html way slower than #render_doc.to_html #141
Description
Not sure if it's commonmarker or underlying lib issue, but still.
Highly scientific benchmark

commonmarker_render_html 8: 2542.5 i/s - 2.66x (± 0.00) slower
commonmarker_render_html 7: 2519.9 i/s - 2.69x (± 0.00) slower
commonmarker_render_html 3: 2498.4 i/s - 2.71x (± 0.00) slower
commonmarker_render_html 0: 2492.0 i/s - 2.72x (± 0.00) slower
commonmarker_render_html 9: 2453.8 i/s - 2.76x (± 0.00) slower
commonmarker_render_html 2: 2429.4 i/s - 2.79x (± 0.00) slower
commonmarker_render_html 4: 2412.7 i/s - 2.80x (± 0.00) slower
commonmarker_render_html 6: 2391.4 i/s - 2.83x (± 0.00) slower
commonmarker_render_html 5: 2371.8 i/s - 2.85x (± 0.00) slower
commonmarker_render_html 1: 2363.0 i/s - 2.86x (± 0.00) slower
so we can easily speedup #render_html 2.5x times by using some more ruby, but I have a suspicion that it should be faster as is.
