Repro Steps:

1) Create a Page
2) Create a Component
3) Create a TextBlock within the Component
4) Create a Dynamic Property in the Component of Name 'Text' and of Type 'String'.
5) Rename the Root of the Component to something unique so that it can be detected in the next steps.
5.5) Close, and ReOpen the Component tab (temporary measure required due to https://www.noesisengine.com/bugs/view.php?id=3207 )
6) Set the TextBlock to be bound to the Dynmaic Property created in Step 4.
7) Navigate to the Page, and place the Component onto the Stage.
8) Set the 'Text' Attached Property of the Component to "HelloWorld".

Observe how "HelloWorld" renders in the Component on the Stage of the Page.

9) Quit Studio completely, and then re-open the project.
10) From the Assets panel, open the Page created in Step 1.

Observe how "HelloWorld" does not render in the Component in the Stage of the Page

11) Close the tab of the Page, and then re-open it from the Assets panel.

Observe how "HelloWorld" now renders as expected.

Expected Result: Components always and automatically render their dynamic properties whenever they are visible on-screen.
