CMDPAL - search in sub folders not working

### Description of the new feature / enhancement

I have many nested folders aka folder within the folder. The filter keywords only seem to be working on the first search results. If I navigate to any subfolder in the search results with ctrl+enter, the filter keywords cease to work.

### Scenario when this would be used?

File and folder search with CMDPAL file explorer extention

### Supporting information

_No response_

Start by reproducing the CMDPAL file and folder search scenario with nested folders: apply filter keywords, then use Ctrl+Enter to open a subfolder. Trace the search and filtering entry points involved in that navigation, and consider the issue done when the same filters continue to work in the opened subfolder.
