The value of the `app_location` is not highlight after editing the `api_location` config value to a space

OS: Win10
Build Version: 20220513.11
Regression: Not a Regression

Repro Steps:

1. Create a static web app using the local project -> Expand the static web app -> Production -> Workflow -> Click the api_location child node -> Edit the config value to a space in the opened .yml file.
   
2. CRTL + S -> Refresh the corresponding "Workflow" -> The api_location value changes to "null" -> Click the app_location.
3. Check whether the value of the app_location is highlight.

Expect:
The value of the app_location is highlight.

Actual:
The value of the app_location is not highlight.

More Info:
On the contrary, this issue doesn't reproduce.

Edit the app_location config value to space in the opened .yml file -> Click the api_location under the "Workflow" -> The value of the api_location is highlight.

Reproduce the issue in the VS Code extension by editing api_location to a space in the opened .yml file, saving, refreshing the Workflow, and selecting app_location. Trace the Workflow tree's value-highlighting behavior for app_location and api_location; done means app_location remains highlighted after the api_location edit, with the opposite edit still working.
