Reminders app shows Chrome against reminder containing web link
I've not noticed this before, so I am assuming that this is something new with El Capitan (but I'm prepared to be wrong).
When I add a reminder using the Share button in Safari, a reminder is created with a web link in the note field. The first few times I did this an icon for Google Chrome appeared on the right —near where the ℹ icon shows. Clicking the Chrome icon would open the link in Chrome. Clicking the web link would open it in Safari.
Now Reminders behaviour has changed again. The Chrome icon is not displayed, instead the little "no entry" symbol is displayed. Nothing happens clicking this, but the link still opens in Safari when that is clicked.
In IOS9 on my iPad, the same reminders are displayed with a Safari icon, which opens the link when clicked. A reminder created on the iPad shows on the iMac with a Safari icon.
Anybody any idea how to configure the app associations in Reminders to fix this small, but irritating little problem?
There doesn't seem to be an appropriate category for Reminders, so I've selected Mail, etc.
