diff compared to main

% python3 -V
Python 3.11.7
% /usr/bin/python3 -V
Python 3.9.6
% ruby -v
ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.arm64e-darwin24]

I don't have the feeling this is dependent of the state of main.

This is coming from 

```

LayoutTests/imported/w3c/web-platform-tests/html/canvas/element/canvas-host/2d.canvas.host.size.attributes.parse.whitespace.html

It contains:

<canvas id="c" class="output" width="&#xD;
        100" height="&#xD;
        100"><p class="fallback">FAIL (fallback content)</p></canvas>


if I check the character  into the characters table, I get U+0020 SPACE

which is indeed in https://github.com/web-platform-tests/wpt/blob/0c59636522/html/canvas/element/canvas-host/2d.canvas.host.size.attributes.parse.whitespace.html
