From 5cf8f0125be62ec47c053d814b00ec98b2142c24 Mon Sep 17 00:00:00 2001 From: audrasjb Date: Thu, 22 Jun 2023 06:01:25 +0000 Subject: [PATCH] Twenty Seventeen: Remove IE specific resources. This changeset switches the `wp_enqueue_*` functions to `wp_register_*` for IE-related resources, which maintains handles, source references, etc., keeps all IE-specific files within the theme package to avoid errors, and requires site admins to opt in to loading them in the theme. It also replace the content of `html5.js` shiv with a comment (to avoid 404s) and removes IE-specific code in general stylesheets. Props desrosj, sabernhardt, audrasjb, neychok, oglekler. See #56699.
