Pull Request Overview

This pull request adds a new unit test file for the WebBrowserUriTypeConverter to enhance test coverage for converting different URI inputs. The key changes include tests for valid URI conversion, handling of empty strings, exception throwing on invalid URIs, and returning the same URI when already provided as a Uri.

Comments suppressed due to low confidence (1)

src/test/unit/System.Windows.Forms/System/Windows/Forms/WebBrowserUriTypeConverterTests.cs:43

• [nitpick] Consider adding a test case for null input to verify that WebBrowserUriTypeConverter handles it appropriately.

Uri uri = new("http://www.microsoft.com/");
