Calling toggle(true) o unfold(true) makes the cell disappear

[Martori]

I'm having trouble with the folding cell on a recycler view. After trying to deal for hours with animation problems, and for testing purposes, I set to true the skip animation booleans to at least try to mitigate the issues I'm having (most of them already reported on other issues). Doing that I found that when I call toggle(true) or unfold(true) on a cell it disappear, but fold(true) does not.
