In the source code of confluence-7.2.0-rc2 (and previous versions), there is a CSS selector like below:
/* from master.css */
.hidden,
li.hidden {
display: none !important;
visibility: hidden;
}
This is overriding a library that I am using. The problem is the selector .hidden
is too broad. display: none
and visibility: hidden
are different. Other tools may rely on one behavior and not the other.
