Safari Dynamic HTML bug

Description

Safari does not update when changing the HTML through Javascript. It uses the old HTML to determine the direction of the element. This is a problem when using :dir() to apply different styles to RTL and LTR languages.

Steps to reproduce

  1. Set the dir attribute of the html element to ltr in the HTML file.
  2. Create a script that changes the dir attribute of the html element to rtl when the page is loaded.
  3. Create a CSS file that applies different styles to an element based on the dir attribute.
  4. Open the HTML file in Safari.

Expected behavior

The element should be styled according to the dir attribute of the html element regardless of the initial value.

Actual behavior

The element is styled according to the initial value of the dir attribute of the html element.

Other information

This works as expected in Chrome and Firefox. The bug is present in Safari 16.4+. I have not tested older versions.
