CSS supports escaping in selectors, e.g. writing `.foo:bar` will match an element with the `foo` class and `bar` pseudo-class, but `.foo\:bar` will match the `foo:bar` class. Our shimmed shadow DOM encapsulation always assumes that `:` means a pseudo selector which breaks a selector like `.foo\:bar`. These changes add some extra logic so that escaped characters in selectors are preserved. Fixes #31844. PR Close #40264
