• Android Runtime: 5.4.0 & 6.0.0
• NativeScript-Angular: 8.0.0 & 8.0.2

Describe the bug
I get "Attempt to use cleared object reference" errors in a few seconds with the MarkingMode = none. (Again: #7125)

You have to change background colors of elements while navigating to a new route several times. After a while it crash.

Use case: Change background color of current route in a menu.

• It don’t crash when you only navigating
• It don’t crash when you only change background color
• It crash when you do both
• It don’t crash when you change text color instead of background color
• It crash quicker when you do lot of calculations in the app

To Reproduce

• Navigate to a new route every second (router.navigate)
• Change Background color of current route in the menu ([class.active]=« … »)
• Overloading the app with other changes (Here other background color changes) (Necessary to accelerate the crash)

Expected behavior
No crash.

Sample project
https://play.nativescript.org/?template=play-ng&id=4RKa1j&v=2
Download it, add "markingMode": "none" in app/package.json under « android » object
Yes, it don’t crash directly in PlayGround.

Additional context
Observed on my application and reproduced in a blank application.
In my app it can crash after 3 or 40 route changes.
