Comment (by westonruter):

 In [changeset:"42192"]:
 {{{
 #!CommitTicketReference repository="" revision="42192"
 Editor: Disable `wp_keep_scroll_position` in IE11 since buggy; fix
 `matches` polyfill conflict with ME.js by doing runtime feature detection
 in context window.

 Props westonruter, SergeyBiryukov, Clorith for testing.
 See #41962, #42029.
 Fixes #42553 for 4.9.
