The k-loading-mask div is now inside the k-content div.
This causes a few issues when it comes to the layout whilst loading.
- The grid is still scrollable
- The loading mask moves up and down whilst scrolling.
Please see the attached gif where i did the following to highlight the issue;
- Used chromes browser throttling mode to emulate a very slow network connection
- Added `background: red` to `.k-loading-mask`
In older versions the loading mask covered the entire grid div and prevent this issue from happening.
