-----------
Trusted Types enforcement in Document.execCommand should be case-insensitive
https://bugs.webkit.org/show_bug.cgi?id=314183
rdar://175852496
Reviewed by Anne van Kesteren and Ryosuke Niwa.
The Trusted Types check in Document::execCommand() was using a case-sensitive
comparison (commandName != "insertHTML"_s) to decide whether to enforce
TrustedHTML. Since execCommand command names are case-insensitive per spec,
passing a differently-cased variant like "InsertHTML" or "inserthtml" would
bypass the Trusted Types enforcement entirely.
Fix by using equalIgnoringASCIICase() for the comparison.
