Describe the bug
The test test_create_title_pattern in test_pattern_application.py fails because it asserts the presence of example.com/docs/page3.html before the data has fully loaded in the delta_urls_table. The failure output shows Loading..., indicating that the test is executing before the table content is available.
Screenshots

Expected Fix
To fix this issue, we need to add a proper wait condition to ensure the table has finished loading before performing assertions.
