+As of 2024, Safari on Apple platforms mis-displays the Bedstead Web
+page. The 'palt' feature is being mis-applied to U+0020 SPACE
+characters. Most of them end up not being narrowed, but some instead
+end up with negative width, as though different layers of the browser
+are calculating the widths of spaces differently. The problem doesn't
+appear to affect any characters other than spaces. Other characters,
+including punctuation, get displayed correctly.
