Very subtle Jira Server behavior changed from 7.4 in regard of CSS?


one of my apps stopped to work since Jira 7.4. It looks like something is affecting to CSS inheritance and “user agent stylesheet” now takes preference whereas missing values were inherited from its parent in earlier Jira versions.

Is there any way to restore old behavior?


Solved. It looks like the change in JIRA 7.4 and above is some .min resources preference:. if x.css.min exists then it is downloaded instead of x.css even x.css is explicitly required to download via the WebRespurceManager. Whereas in 7.3 x.css and not x.css.min was downloaded.

On the other hand, my app integrates a complex 3rd party application with x.css and x.css.min having minimal differences causing the issue…
