Probably misunderstanding how feed filters work

[pdxmph]

Describe the bug
Using the url.contains filter doesn't seem to work, but its inverse does. I am guessing I am missing how this is supposed to work.

To Reproduce
Steps to reproduce the behavior:

1. Edit a feed
2. Set up a filter to capture URLs with advice in them (url.contains('advice'))
3. Refresh the feed.
4. Nothing is marked as read, including things that have advice in the URL.
5. Revisit the filter and negate it with not url.contains('advice')`
6. Refresh. Everything but advice columns is marked read.

Expected behavior
url.contains('advice') will mark anything with advice in the URL as read. Use case: My local paper puts all the advice columns under https://oregonlive.com/advice/foo.

Environment (please complete the following information):

• CommaFeed version (or "commafeed.com"): 4.3.1 (fafd4c9)
• Browser [e.g. chrome, firefox]: Firefox
• Device [e.g. desktop, mobile]: Desktop (Linux, Fedora 39)

Additional context

Hi @pdxmph,

3. Refresh the feed.

The filter only applies to new entries, changing the filter and refreshing the feed will not mark existing entries as read.

Refresh. Everything but advice columns is marked read.

I'm not sure how that's possible :D

There's an issue here to apply the filter to existing entries #728
