The languagesettings dialog does not open when clicking the
uls.trigger for the first time. This issue occurs when the user is
not logged in, ULSPosition is personal, and ULSAnonCanChangeLanguage
is false.
Without this change, the following happens:
* uls.languagesettings is loaded via uls.interface
* uls.languagesettings::hide is called via uls.languagesettings::init
* click method is triggered immediately via script in uls.interface
* uls.languagesettings::show is called
* uls.languagesettings::hide is called - triggered via ::show
method - $( document.documentElement ).trigger( 'click' ); but
dialog is not visible yet, so this does nothing
* uls.languagesettings::show displays the uls.languagesettings
* hide method called again via click handler for documentElement
With this change in place the hide method is not called again due to
e.stopPropagation();
Additionally add a parameter autoOpen that can be set to open the dialog
automatically.
