 In [changeset:"51107" 51107]:
 {{{
 #!CommitTicketReference repository="" revision="51107"
 Widgets: Prevent infinite loop in PHP8+ if the URL for the widget instance
 is incorrectly defined

 This checks to make sure $link isn't empty before attempting to manipulate
 it.  A simple test to demonstrate this can be seen at
 https://3v4l.org/PgSZg. Unit tests for both what already works and what is
 fixed by this change.

 Props hellofromTonya, dd32, peterwilsoncc.
 Fixes #53278.
