Static homepage URLs not redirecting

[lcaple]

When setting a static page for your site homepage, the site does not automatically redirect to the homepage URL if visited. Example: your.site/the-homepage should automatically redirect to your.site/ when set as the homepage in Dashboard > Settings > Reading.

We've implemented this specifically in class.install.php based on these issues impacting our sites:
4.5 causes infinite redirect on static front page
Infinite redirect problem WP4.5 2014 Theme 1.7

Would like to test and investigate whether or not this bug has been fixed in WordPress core in 4.9.x and later. Marking this as a bug despite working as intended since it's implemented as a bugfix.
