Given the following input:

plain <b>bold <i>italic bold </b>italic </i>plain

htmlparser2 generates events equivalent to the following:

plain <b>bold <i>italic bold </i></b>italic plain

whereas the HTML5 spec (and de facto HTML behavior pre HTML5) interprets it as the following:

plain <b>bold <i>italic bold </i></b><i>italic </i>plain

You can confirm this behavior by opening the attached file in your browser and then looking at the rendered results as well as inspecting the DOM. This is also specified by the HTML Living Standard: 13.2.10.1 Misnested tags: <b><i></b></i>. See also https://stackoverflow.com/a/8766163/8910547

expected behavior

The current behavior with the following changes:

1. Generate an implied <i> open tag event between the </b> close tag and "italic " text events.
2. Do NOT skip the </i> close event between the "italic " and "plain" text events.
