Filter bar not working

I'll be happy to provide any other useful info that can help to solve the issue.

Reproduced via:

• Add a property/frontmatter to a page with a null value
• Input a filter string that doesn't match the page's path or tags, so that matchFilter attempts to look for a match in other page metadata (if the path or tags match, matchFilter won't bother looking at other metadata, so the null won't be encountered).

Fix coming soon.
