Pull Request Overview

This PR fixes an issue with closing popups when the escape key is pressed in a mixed environment of OpenUI5 and UI5 Web Components. The fix ensures proper event handling and prevents interference between OpenUI5 and Web Component popup escape key behavior.

Key changes:

• Added event marking utilities to prevent conflicts between popup systems
• Modified popup registry to check for marked events before handling escape
• Updated ComboBox escape key handling to be more selective about propagation
