Filtering lost when navigating out of requirement/test/test set

Hi all,

We've been noticing an intermittent issue over the last 2-3 months whereby filtering (perhaps the wrong word to use) is being lost when navigating back from a requirement, test or test set to the listings page. 

For example, if I've been editing a test and then navigate back to the listings page (where all tests in the folder are shown), instead of displaying just the tests in the particular folder that I've been working on, the filtering is lost and ALL tests are shown. 

This is an intermittent issue and has been impossible to nail down the exact conditions that casue it to occur, however, we think it started happening after the change that allows multiple sessions to be open at once.

Has anyone else experienced this?

Many thanks,

Elliott.
