Problematic modules: {"ext.CookieWarning.styles":"error"}
*/What should have happened instead?:
styles are loaded correctly
Software version :
- MW 1.39.6
- CookieWarning 3a652de0d24e6d38327cb5f08d3143535f4e71f7
- probably since the "fix z-index" commit in CookieWarning
I placed the mediawiki.skin.variables.less into my skin and imported the default styles via @import 'mediawiki.skin.default.less';. However in MW 1.39.6 the mediawiki.skin.default.less does not contain a variable @z-index-overlay. When i add the variable into mediawiki core's mediawiki.skin.defaults.less everything works as expected.
