1.9.1: Hidden companion files in filter results

[moropus]

XnView: MP 1.9.1 64 bit
OS: Windows 10 64bit

When using search dialog from Quick Filter, the search results shows and counts companion files.
The reproduction here is on 2 files only, but I've got hundreds of RAWs with XMPs, and search results are cluttered with incorrect data.

To reproduce:
1. Select option Hide companion files in Options
2. Make a file.jpg with companion file.xmp
3. Search for file.jpg in Quick Filter:
- click ... in Quick Filter
- type 'file' to Filename
- click ... and select current folder
- click search

Actual behaviour (bug): 2 results found, including file.jpg and file.xmp
Expected behaviour: 1 result found file.jpg

4. Click Browse and see only one file

The bug doesn't reproduce on every companion, looks like the structure of the companion file somehow matters.
Attached the files with reproduction (folder.zip).
