HTML hidden attribute overridden by ui class?

[ultimodruido]

It seems that the "hidden" attribute is not considered by the browser when a tag has the "ui" class.

Examples:
This element is visible
<div class="ui placeholder segment" hidden><h1>Content #1</h1></div>
Removing only the "ui" class makes this element disappear.
<div class="placeholder segment" hidden><h1>Content #1</h1></div>

Tested in Opera 67

Yes, it's because any ui element changes the display css value which itself overrides any existing hidden-property

By adding the following small line of CSS code, you should be able to force the hidden-property to gain more respect

[hidden] { display:none !important;}
