DynamicSizeMode="Content" Causes app freeze on iOS

[Matt]

I am using an sfAccordion in my app. If I set size to dynamically expand, I can expand it once, and then as soon as I collapse it, the app freezes. If I leave it expanded the app remains usable.

If I remove DynamicSizeMode="Content", I can expand and collapse the accordion as many times as I like and the app does not freeze.

The issue only affects iOS and does not occur on Android.

Here is a code sample [EDIT: Not sure why the closing tag symbols get stripped out at the end, i.e. < / , but they are there in the original code]

<sfa:SfAccordion x:Name="AttachmentAccordian"

                 IsVisible="{Binding HasAttachments}"

                 ExpandMode="SingleOrNone"

DynamicSizeMode="Content">
