Filtering Page List via Topic List block not working

Description

I've added a page list block to a page. I've ticked Enable Other Blocks to Filter This Page List. I've added a Topic List block to the page. If I set it to Mode: Page, it lists no topics – even though the pages in the page list all have topics set. If I set it to Mode: Search, it doesn't filter the Page List block.

I'm using Modena as the theme. The page list block is set to the Default template so it's not an ovveride issue.

How to reproduce

1. Add a page list block to a page.
2. Tick Enable Other Blocks to Filter This Page List.
3. Add a Topic List block to the page.
4. Save the page
5. Click on a Topic that you know doesn't match any page in the Page List - it still displays all pages
