Test Run order is not consistent when tests are updated

The Test Runs may be displayed in a different order after executing.

To reproduce, create a Test Execution with >20 test runs. The tests must have a field that has the same value for different tests (for this example, Summary). In the Test Run Table of the Test Execution, order by Summary and make sure that the table is displaying 10 rows only. 

Using the bulk change functionality, select the current page and execute the Test Runs to any different status.

The Table will refresh and the test runs displayed may not be in the same order.

This happens because the sorting field "summary" contains the same value for various issues, so the order of the Tests may not be the same as it relies on Jira JQL to resolve the 'tie' between issues with the same value.
