This comes up while working on issue 41748 browser input data:text/html,<!doctype html><div class="bar" class="foo">text</div> browser output <div class="bar">text</div> Actual HTMLParser output see https://github.com/python/cpython/pull/24072#discussion_r551158342 ('starttag', 'div', [('class', 'bar'), ('class', 'foo')])] Expected HTMLParser output ('starttag', 'div', [('class', 'bar')])] |

If we follow the behavior of the browser, we will have to pick one of the two values and discard the other, making this value unaccessible. If we provide both, scripts and libraries that use HTMLParser will have access to both and can decide what to do.
For example BeautifulSoup already does the right thing:
>>> bs4.BeautifulSoup('<!doctype html><div class="bar" class="foo">text</div>')
<!DOCTYPE html>
<html><body><div class="bar">text</div></body></html>
Changing this might also break code that rely on this behavior. I'm therefore going to close this as "not a bug".
