Current behavior:
In my application, I use VirtualScroll and infiniteScroll.
Occasionally the height of VirtualScroll will not be updated and the following record may be hidden.

Related code:

https://github.com/ionic-team/ionic/blob/master/src/components/virtual-scroll/virtual-util.ts#L533

In the current code, the height of VirtualScroll is mother number of denominator. Then, as the height becomes very high, the response to the update of the height becomes bad.

The situation in my application is as follows.

• lastCell.record: 135
• totalRecords: 143
• percentToBottom: 0.9507042253521126

percentToBottom > .995 => false

• newHeight: 33356
• diff: 4408
• difference: 0.25 (fixed value)

diff > (newHeight * difference) => false

Despite the addition of 4408px in height, the height of VirtualScroll did not change.

Hello, thanks for using Ionic! I am going to close this issue as a duplicate of #9765

@jgw96 Thanks for your response. But, this issue is different #9765. This problem is occurring in ionic 3.3. Please confirm again.

I am sorry that English is not good and it is difficult to understand. ;-)
