Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 7.2.0
• Cross-platform modules: 7.3.0
• Android Runtime: 7.0.1
• iOS Runtime: -
• XCode Version: -
• Plugin(s): -

Describe the bug
When navigating from page A to page B and page B has an ActionBar with a different background-color than page A and the user navigates back from page A, the ActionBar of page A has now the background-color of page B until you navigate forwards to page A.

• This is NOT happening on iOS
• This was not happening with @nativescript/core 7.1.4 -> issue exists since 7.2.0, probably caused by Faster background color #9120

Not sure if it is related only to the ActionBar, but it is the only thing I noticed from our real app at least, the other widgets seem not to be affected.

<!-- page A -->
<Page>
    <ActionBar title="Main page" backgroundColor="CadetBlue" color="white"/>
</Page>

<!-- page B -->
<Page backgroundColor="black">
    <ActionBar title="Detail page" backgroundColor="black" color="white"/>
</Page>

To Reproduce
follow the steps from the GIF with the sample app provided below

Expected behavior
When navigating back to page A, the ActionBar should have the background-color defined in xml or css, not the background-color from the page B.
