Bug ID: 49448
           Summary: mshtml detects wrong HTML charset

html with incorrectly detected charset

Charset of some HTML files gets detected incorrectly. Example of the
problematic HTML is attached.

When correctly rendered it should render as "АБВГД - Кириллица".

On the mailing list Jacek asked to test with IE, Firefox 47 and builtin Wine's
iexplore: the result is that IE renders this HTML correctly while Firefox
47.0.2 and Wine's iexplore render it using wrong charset. Chrome 83.0.4103.116
under Windows 10 and Chromium 83.0.4103.61 under Linux render this HTML
correctly.

This looks like a bug in Gecko, so the Product field of this bug report could
be changed if desired.
