Description Henri Sivonen 2021-03-15 01:12:39 PDT

Steps to reproduce:

1. Load https://hsivonen.com/test/moz/xml-decl/kilobyte-plus-one-after.htm

Expected results:

Expected the character after "Test: " not to be ж. I.e. expected the XML declaration in text/html not take effect when its terminating greater-than sign is not within the first 1024 bytes.

Actual results:

The XML declaration syntax takes effect for character encoding indicating that the greater-than sign was scanned for past the first 1024 bytes.

Comment 2 Domenic Denicola 2021-05-06 10:44:21 PDT

The spec PR has been updated to no longer have this limit; I suggest closing.

Comment 3 Ahmad Saleem 2023-09-26 17:29:13 PDT

All browsers (Safari 17, Chrome Canary 119 and Firefox Nightly 120) all render the test case same.

Also Comment 02 suggests, we can close this?

@Anne - any input?
