(0) Install non english languages and RTL languages too as German or Spanish and Hebrew (rtl) logout and look at login page. Part A : left-to-right languages 1) i) test that no clipping happens (as in screenshot) to long labels for ['username'] and ['password'] . (you can also make the word there very long by editing the html or lang file) ii) test that no wrapping to those labels happen when the window is made smaller. 2) test (1) in all core themes in the master branch. In master branch test also that the 'remember username' is centralized and doesn't wrap unnecessarily. 3) test (1) in all core themes in affected stable branches. (if fix is applied there) 4) include testing this in different browsers and at different screen resolution (From Sam's last peer-review comment) Part B : perform (1 - 3) but with RTL languages this time. (hint: lang/en/langconfig.php -> direction -> 'ltr' can be tweaked too)
