Bug 226168

Summary:	WebKit renders XHTML files using HTML parser
Product:	WebKit	Reporter:	John A. Bilicki III <jab_creations>
Component:	XML	Assignee:	Nobody <webkit-unassigned>
Status:	RESOLVED INVALID
Severity:	Normal	CC:	ap, cdumez

Version:	Safari 14
Hardware:	All
OS:	macOS 11

Description John A. Bilicki III 2021-05-24 01:27:08 PDT

I encountered and reported a bug earlier and created an XHTML file as a test case:
https://bugs.webkit.org/show_bug.cgi?id=226148

HTML parsers will return fully uppercase strings when referencing nodeName.
XML parsers will return fully properly cased strings when referencing nodeName (e.g. table for table, Table for Table).

XHTML files should be rendered using the XML parser, not the HTML parser.

I think the implied steps to reproduce are:
1. Open https://bugs.webkit.org/attachment.cgi?id=429442
2. Press a key
3. Observe an upper case tag name instead of lower case.

I cannot reproduce this in Safari, and also I'm pretty certain that WebKit uses XML parser for application/xhtml+xml.
