663 - Filter issue if plain view enabled 2

[Dreamer]

- go to folder with subfolders
- create file aaa.bbb.ccc.ddd in any subfolder
- go to subfolder with the file aaa.bbb.ccc.ddd
- enable quick filter, type "bbb"
= file is filtered correctly

- now go up ( [..] ) one folder
- enable plain view files + folders or plain view files
- file aaa.bbb.ccc.ddd is listed
- enable quick filter, type "bbb"
= file is NOT filtered at all

The issue appears with any files with 2 or more dots in the name, only if plain view is enabled.
