Items with images disappears in Endless scroll mode

[Maxim]

Hello,

I have a list view with Endless scroll mode enabled. My list items have relatively big height (more than a half of page height) and have images.
Then I scroll an item the bottom of the item reaches list view top, the rest visible portion of the item gets disappeared. 
You can see this behavior here: http://dojo.telerik.com/eJuB/3

If items does not have any images - it works fine. Item can be scrolled from top to bottom and its internals are visible all the way.

Is it a bug? How can I prevent the item from erasing until it fully gets out of the view?

Thank you

Hi Maxim,

I have tried to reproduce this issue in a Chrome and IE10 browser, but to no avail, please check the following screencast and let me know if I missed something:

What is the browser/device that you are testing on, how can I reproduce the issue?

I can reproduce it on IE 11 (desktop), Latest Chrome (both desktop and Android 4.0, 4.1, 4.2).
My QA team can easily reproduce it too on a various devices.

As a guess, may be you should try a smaller window size? Also data disappears after a short delay (about 0.5 ms). On desktop is easily reproducible by scrolling with mouse wheel slowly, "click by click".

Hi Maxim,

The behavior you observe is due to the virtualization implementation - items above certain threshold (actually, half of the page height) are removed and recycled at the bottom to facilitate new items. I think that this may be tweaked to avoid removing items which are still visible, and have logged it for future investigation.
