SUMMARY
When using the filter bar, navigating into a folder within the filter results, then returning back, the filtered view is reset. The filtered view should return if I click back.

STEPS TO REPRODUCE
1. Launch Dolphin
2. Use filter bar (CTRL-I) and type in a keyword. Keywords filter results in view.
3. Double click a folder to view the contents.
4. Click back

OBSERVED RESULT
Filtered results are lost when navigating into a filtered result folder and clicking back.

EXPECTED RESULT
The filter should return, because that is a crucial step in the navigational history. If clicked back again, the previous state should also return, whether it be a previous filter prior. Essentially any filter should become part of the navigational history within Dolphin.
