Why yii2 terrible lag jquery hide and show?

Hello. Here's a primitive https://jsfiddle.net/34h8d3ut/1/ select terrible lag, if you use it in yii2. On a normal website, or in jsfiddle works fine, no lag, but in yii2, something incredible happens. The animation of the appearance and disappearance takes about 4-5 seconds. Observed this in 3 browsers. Yii clean, just installed. What could be the problem?

He's not in Yii2 lag and on the page, which gives Yii2, it should look for the problem.
I'd advise against profiling because he actually has never used and don't really want, but the usual debugging to be able necessary.

Yii clean, just installed.

And page also clean, or problem specific "widget"?
The animation of the appearance and disappearance takes about 4-5 seconds.
Need to watch those scripts which it produces, removing them one by one, perhaps "crooked" decision like hooks for these functions and slow down.
Another way to debug jQuery myself but it is difficult later if required.
And sometimes the problem is not where you are looking for, maybe just CPU load is high due to something else. :)
I told the truth when I say that yii is clean. The "pure" yii I had screwed my css styles. It turned out that these lines can cause lag:
* {
 -webkit-transition: all 0.18 s ease-in-out;
 -o-transition: all 0.18 s ease-in-out;
 -moz-transition: all 0.18 s ease-in-out;
 transition: all 0.18 s ease-in-out;
 }
