Environment

• CLI: 5.2.4
• Cross-platform modules: 5.2.2
• Android Runtime: 5.2.1
• iOS Runtime: 5.2.0
• Nativescript Angular

Describe the bug
On IOS, navigating to a page results in the page content not extending to the action bar and leaving a large gap of white space. User input such as a tap event will cause the page the redraw into the correct format without the white space.

To Reproduce
I honestly don't have a clue what specifically makes this bug occur. I suspect its related to recently upgrading to "tns-core-modules: 5.2.2" as we weren't having these issues a few weeks ago, but I could be wrong. The best I can give you is that it happens on initial page load and persists until you interact with the page, at which point the page will be formatted correctly.

If it helps, we are also using flat="true" on all of our action bars.

Additional context
An example can be found here.

EDIT 1
I'm in the process of switching back to 5.2.1 to confirm my suspicions. As a work around, adding "changeDetectorRef.detectChanges()" at the end of the ngOnInit function seems to fix the problem, but I'm hoping to find a solution that doesn't involve injecting that into every single page.

EDIT 2
We confirmed that the issue exists only on tns-core-modules v5.2.2, reverting back to 5.2.1 solves this.
