#29167 new Bug

HashedFilesMixin doesn't work with data URIs that include a closing parenthesis

My team recently started using Bootstrap 4, and some of their styles get broken by the regex patterns in HashedFilesMixin ( This is loosely related to #21080.

For example, this is one of the rules in the generated Bootstrap 4 CSS, and the current regex incorrectly mistakes the closing parentheses in rgba(0, 0, 0, 0.5) as the end of url():

.navbar-light .navbar-toggler-icon {
  background-image: url("data:image/svg+xml;charset=utf8,%3Csvg viewBox='0 0 30 30' xmlns=''%3E%3Cpath stroke='rgba(0, 0, 0, 0.5)' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 7h22M4 15h22M4 23h22'/%3E%3C/svg%3E");

Not an ideal solution, but we were able to work around this issue by Base64 encoding these data URIs.
