[Android] RecycleElement List: using bindings for FormattedText results in "requestLayout() improperly called" issues

[endarea]

Description

I have a list with CachingStrategy set to RecycleElement. When using bindings for a label's FormattedText the console is filled with messages like requestLayout() improperly called by {...}.FormsTextView{...} during layout: running second layout pass

Steps to Reproduce

1. Create a List with CachingStrategy set to RecycleElement
2. Add simple cells: a label with FormattedText linked to a bindable property in the view model
3. Fast scroll up and down

Expected Behavior

The list should scroll smoothly with no errors

Actual Behavior

Application Output is filled with messages like the one above. The scroll's behavior doesn't seem to be impacted when the debugger is not connected. These messages are not displayed when binding to a CLR property which creates a new FormattedString() instance on each get or when using RetainElement as a CachingStrategy.

Basic Information

• Version with issue: Xamarin.Forms 3.1.0.637273
• Last known good version: ?
• IDE:
• Platform Target Frameworks:
  • Android: 8.1
• Affected Devices: I can name Huawei Nexus 6P (API 27) but it happens on other devices too

I had a little bit of an issue recreating this but was able to with a Nexus 6P API 27 Emulator

I ran into this problem today. In my case, the console message was generated continuously in an infinite loop unless I stopped the debugger. It was coming from LabelRenderer, and I was using a plain Label without FormattedText.

Any news/workaround?

This issue makes app very laggy and stops us from updating to 3.1 and later
