PageType decorated URLs do not get type parameter added when default is not empty
The solution for #87817 works only for empty defaults, not for non-empty defaults. The default must be allowed to be non-empty and still allow the type parameter for different typeNum.
PageTypeSuffix: type: PageType default: '.html' index: 'index' map: 
Currently links to type > 0 will just create urls like
/my/path/to/site.html - but of course they still need to append the type parameter
?type=123 to work correctly.
This is because resolveValue() returns the default and afterwards it is checked if the returned value is empty (which it never is if a default is set).
