Wrong URL and Title are stored on some web pages

### Steps to reproduce
1. Go to one of Doist articles, for example the one on [networking](https://blog.doist.com/virtual-networking/)
2. Make a couple of highlights / annotations
3. Check your hypothesis dashboard

### Expected behaviour
I expect to see the article named "How to Make Virtual Networking Less Cringey (With Real-Life Examples to Help)" with all the highlights from that page.

### Actual behaviour
Instead I see an entry for a different blog post ("7 Ways to Support Your Team During the Pandemic — And Any Crisis" in my case) and a different URL. The highlights and annotations make sense, but the title and URL don't. This is interesting since when I go the correct page I do see all the annotation in the sidebar.

### Browser/system information
I am using:
- Vivaldi | 3.7.2218.58 (Stable channel) (x86_64)
- OS | macOS Version 10.15.7 (Build 19H524)

### Additional details
I checked the Source Code for the Networking page and so no reference to the other blog post that actually was registered.
