Starting with saved theme URL and applying gloss_wave background loses all settings #594
Description
Description
If I retrieve the ui url from the css header (see below links) and I try to edit the background of a style by applying the gloss_wave, I loose most of the style and I obtain a rendering based on the default theme.
If the url comes from an old theme version it is rendered correctly but cannot be modified (see the above explanation)
If I "save as" the current theme with the latest version, the link available on the theme css do not produce the expected theme but always the default theme.
A downloaded theme do not take into consideration a scope (if, any) because the index.html should associate to the body a class with the scope name.
In general, at this stage, the theme roller is unusable.
Link to test case
The below theme urls should be equivalent.
This is a 1.11.4 custom theme (this works but cannot be modified):
This is the 1.13.1 version of the previous theme (this doesn't work at all):
