Extended Description

The HTML file generated by the Clang Static Analyser (version 10.0.0) has an issue with the nesting of closing tags. I have attached one such HTML file. In this file, at line 2314, the placement of closing of outermost tr and td tags is incorrect.

As a result, HTML parsers like jsoup and pup fail to read the HTML file past the line number 2314.

HTML validator reports issues with all the line numbers beginning from 2315 until the end of HTML file.

I manually fixed the issue and then the parsers were able to parse the entire HTML file.

Contributor guide

Research direction
Examine the HTML report generation code in Clang Static Analyzer, focusing on how closing tags for <tr> and <td> are emitted. Trace the logic that builds the table structure and identify where the nesting order is incorrect.
