WIP: Noissue - Reenabled selector-no-qualifying-type stylelint rule
requested to merge ThomasGreiner-eyeo/abp/ui/adblockplus:noissue_reenable-stylelint into release-2018-4
This is a follow-up to https://gitlab.com/eyeo/adblockplus/adblockplusui/issues/79 to enable the "selector-no-qualifying-type" stylelint rule. However, seeing the changes that it requires, I'm not as confident anymore whether we should enforce this rule because (a) it may break existing code and (b) it doesn't allow referring to specific tags in cases where we'd like to (e.g. body.nohtml). Also note that this rule is not part of our coding style.
Therefore please let me know what you think about this rule.
