Using firefox, we have a ScrollView where each item has a checkbox. If you select an option from the top of the web page, then scroll down to the bottom of the page, anything that was checked at the top of the page is now unchecked. The same works the other way, check something at the bottom, scroll back up and when the selection is no longer available in the view area the item becomes unchecked.
To clarify, is this a ScrollView with a ListView inside?
And just to make sure, you're not using CollectionFastPath are you?
No, I am not.
An extremely cursory attempt at reproduction has failed. Is this still an issue?
