A number of icons in the icon library are redrawn with the `rect` and `circle` elements. `WP_Icons_Registry::sanitize_icon_content()` allows the `svg`, `path` and `polygon` tags only, so `wp_kses()` removes both elements before the icon is stored or returned. This adds `rect` and `circle` to the allowlist, carrying the same presentation attributes the existing shapes have along with the geometry attributes each element needs. Props wildworks, retrofox. See #66101. Fixes #66112. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Backports Gutenberg PR #82846 to the Core icon registry.
A number of icons in the icon library are redrawn with the
rectandcircleelements, butWP_Icons_Registry::sanitize_icon_content()allows thesvg,pathandpolygontags only, sowp_kses()removes both elements before the icon is stored or returned. Icons registered by plugins and themes throughwp_register_icon()are affected today, and the redrawn library icons will lose part of their shape once they are synced to Core.Both new entries carry the presentation attributes the existing shapes already have, plus the geometry attributes each element needs.
Notes:
rectandcircleneed to carry them as well, since the two elements are drawn with strokes in the library today.focusableis not included. It is meaningful on thesvgroot element only, and the entry onpolygonis a leftover from the Twenty Twenty allowlist this list was copied from.Trac ticket: https://core.trac.wordpress.org/ticket/66112
