PBT Extension - Test summary with history - Filter

The filter for this tree view will work the same way as the filter in the test tree view. Once a filter option is selected from the menu the the @ symbol and the filter key word will be applied to the filter input field.

Start by locating the existing test tree view filter implementation and compare its behavior with the test summary history tree view. The work is done when selecting a filter option applies the @ symbol and filter keyword to the filter input field in the summary history view.
