Project Explorer view is not refreshed after change of Build Configuration

Description
Project Explorer view is not refreshed after change of Build Configuration

To Reproduce
Steps to reproduce the behavior:

1. Create simple (unmanaged) C/C++ project with at least two build configurations and with common folder used in both build configurations, one resource (folder) used in one build configuration and another resource (folder) used in another configuration.
2. Configure resources appropriately so every Build Configuration includes only necessary resources.
3. Refresh Project Explorer view using either F5 key or pop-up menu.
4. Switch build configurations
5. See Project Explorer view still shows resource(s) specific for previous Build Configuration as available while resources of active Build Configuration greyed (unavailable)
6. Refresh Project Explorer view manually using either F5 key or pop-up menu.
7. See Project Explorer shows resources as expected for active Build Configuration
8. Repeat steps 4 through 7

Expected behavior
Project Explorer changes view of resources on change of active Build Configuration as it were in earlier versions.

Version Information (please complete the following information):

• Windows 11 Enterprise 24H2
• Eclipse IDE for C/C++ Developers (includes Incubating components) Version: 2025-06 (4.36.0) Build id: 20250605-1316
• C/C++ Development Tools 12.1.0.202506041907

Attempt to reproduce in such a simple configuration failed. Perhaps it depends on the size of the project or maybe due to workspace change after Eclipse update. Still doesn't work in real project.

It appeared that whether Project Explorer view is refreshed or not depends on whether C/C++ Elements are enabled in Filter and Customization dialog on tab Content.
It is weird and I believe it needs to be changed so that Project Explorer view is refreshed every time Build Configuration is changed in order to reflect possible change of Build Configuration resources.

Project Explorer changes view of resources on change of active Build Configuration as it were in earlier versions.

Do you know about which version things changed in?
