Hi,

many thanks for your excellent layout, the experience is very good.

this week I got below error in my project sometimes and did not know what cause the issue,

So i copy code of demo of controlled-layout and config those tabs to cached.

(tabs: [{id: 't3', cached: true}, {id: 't4', cached: true}, {id: 't5', cached: true}, {id: 't6', cached: true},{id: 't7', cached: true}, {id: 't8', cached: true}, {id: 't19', cached: true}, {id: 't10', cached: true}])

then drag tab t3 to right side of t5 and repeat the action quickly.

try for few times or sometimes more than ten times, the layout page crash and get below issue.

could u please have a try and help to fix,

many thanks.
