When using the search box to find a test, the autocomplete suggestions are case-sensitive, meaning that tests only populate if the case typed matches the start of a test name. REPRODUCIBILITY: 1. For this example, suppose we are trying to find the test TestWebKitAPI.WKWebExtensionAPITabs.PortDisconnectWithMultipleListeners. 2. Start typing and get to the following: TestWebKitAPI.WKWebExtensionAPITabs. 3. Type a lowercase p. RESULTS: - Expected: the example API test populates as an autocomplete suggestion. - Actual: the test is not shown in the list of autocomplete suggestions.
