page-slug.php template not working for static front page

[thomask]

if you set static front page, the page-[slug].php template not working.
E.g. if you create page with ID 2 with slug "homepage" with standard settings - www.example.com/homepage, than page-homepage.php template is used. But if you set static frontpage, it does not work (but you can still use page-2.php template).

P.S.: it would be great, if we could use also home.php for this page (anyway everyone can have only one frontpage, so if you have home.php in your template directory, it mean you want it as a home)

(In [14152]) Fix page-<pageslug>.php templates for static front pages. See #12907

as for home.php, See #12593, #7715, #6801
